1.3 Description
The AM335x microprocessors, based on the ARM Cortex-A8 processor, are enhanced with image,
graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. The
devices support high-level operating systems (HLOS). Linux®and Android™ are available free of charge
from TI.
The AM335x microprocessor contains the subsystems shown in the Functional Block Diagram and a brief
description of each follows:
The contains the subsystems shown in the Functional Block Diagram and a brief description of each
follows:
The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor and the PowerVR
SGX™ Graphics Accelerator subsystem provides 3D graphics acceleration to support display and gaming
effects.
The PRU-ICSS is separate from the ARM core, allowing independent operation and clocking for greater
efficiency and flexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocols
such as EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos, and others.
Additionally, the programmable nature of the PRU-ICSS, along with its access to pins, events and all
system-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specialized
data handling operations, custom peripheral interfaces, and in offloading tasks from the other processor
cores of SoC.

4.2 Pin Attributes
The AM335x and AMIC110 Sitara Processors Technical Reference Manual and this document may
reference internal signal names when discussing peripheral input and output signals because many of the
AM335x package terminals can be multiplexed to one of several peripheral signals. The following table
has a Pin Name column that lists all device terminal names and a Signal Name column that lists all
internal signal names multiplexed to each terminal which provides a cross reference of internal signal
names to terminal names. This table also identifies other important terminal characteristics.
(1) BALL NUMBER: Package ball numbers associated with each signals.
(2) PIN NAME: The name of the package pin or terminal.
Note: The table does not take into account subsystem terminal multiplexing options.
(3) SIGNAL NAME: The signal name for that pin in the mode being used.
(4) MODE: Multiplexing mode number.
a. Mode 0 is the primary mode; this means that when mode 0 is set, the function mapped on the terminal corresponds to the name of
the terminal. There is always a function mapped on the primary mode. Notice that primary mode is not necessarily the default
mode.
Note: The default mode is the mode at the release of the reset; also see the RESET REL. MODE column.
b. Modes 1 to 7 are possible modes for alternate functions. On each terminal, some modes are effectively used for alternate
functions, while some modes are not used and do not correspond to a functional configuration.
(5) TYPE: Signal direction
I = Input
O = Output
I/O = Input and Output
D = Open drain
DS = Differential
A = Analog
PWR = Power
GND = Ground
Note: In the safe_mode, the buffer is configured in high-impedance.
(6) BALL RESET STATE: State of the terminal while the active low PWRONRSTn terminal is low.
0: The buffer drives VOL (pulldown or pullup resistor not activated)
0(PD): The buffer drives VOL with an active pulldown resistor
1: The buffer drives VOH (pulldown or pullup resistor not activated)
1(PU): The buffer drives VOH with an active pullup resistor
Z: High-impedance
L: High-impedance with an active pulldown resistor
H : High-impedance with an active pullup resistor
(7) BALL RESET REL. STATE: State of the terminal after the active low PWRONRSTn terminal transitions from low to high.
0: The buffer drives VOL (pulldown or pullup resistor not activated)
0(PD): The buffer drives VOL with an active pulldown resistor
1: The buffer drives VOH (pulldown or pullup resistor not activated)
1(PU): The buffer drives VOH with an active pullup resistor
Z: High-impedance.
L: High-impedance with an active pulldown resistor
H : High-impedance with an active pullup resistor
(8) RESET REL. MODE: The mode is automatically configured after the active low PWRONRSTn terminal transitions from low to high.
(9) POWER: The voltage supply that powers the I/O buffers of the terminal.
(10) HYS: Indicates if the input buffer is with hysteresis.
(11) BUFFER STRENGTH: Drive strength of the associated output buffer.
(12) PULLUP OR PULLDOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor. Pullup and pulldown resistors can
be enabled or disabled via software.
(13) I/O CELL: I/O cell information.
Note: Configuring two terminals to the same input signal is not supported as it can yield unexpected results. This can be easily prevented
with the proper software configuration.

4.3 Signal Descriptions
The AM335x device contains many peripheral interfaces. In order to reduce package size and lower
overall system cost while maintaining maximum functionality, many of the AM335x terminals can multiplex
up to eight signal functions. Although there are many combinations of pin multiplexing that are possible,
only a certain number of sets, called I/O Sets, are valid due to timing limitations. These valid I/O Sets were
carefully chosen to provide many possible application scenarios for the user.
Texas Instruments has developed a Windows-based application called Pin Mux Utility that helps a system
designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. The
Pin Mux Utility provides a way to select valid I/O Sets of specific peripheral interfaces to ensure the pin-
multiplexing configuration selected for a design only uses valid I/O Sets supported by the AM335x device.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to their associated VSS or VSSA_x.
(3) Not available on the ZCE package. VDD_MPU is merged with VDD_CORE on the ZCE package.
(4) This supply is sourced from an internal LDO when RTC_KALDO_ENn is low. If RTC_KALDO_ENn is high, this supply must be sourced
from an external power supply.
(5) During functional operation, this pin is a no connect.
(6) Not available on the ZCE package.
(7) This terminal is connected to a fail-safe I/O and does not have a dependence on any I/O supply voltage.
(8) This parameter applies to all I/O terminals which are not fail-safe and the requirement applies to all values of I/O supply voltage. For
example, if the voltage applied to a specific I/O supply is 0 volts the valid input voltage range for any I/O powered by that supply will be
–0.5 to +0.3 V. Apply special attention anytime peripheral devices are not powered from the same power sources used to power the

respective I/O supply. It is important the attached peripheral never sources a voltage outside the valid input voltage range, including
power supply ramp-up and ramp-down sequences.
(9) This terminal is connected to analog circuits in the respective USB PHY. The circuit sources a known current while measuring the
voltage to determine if the terminal is connected to VSSA_USB with a resistance less than 10 Ωor greater than 100 kΩ. The terminal
should be connected to ground for USB host operation or open-circuit for USB peripheral operation, and should never be connected to
any external voltage source.
(10) Based on JEDEC JESD78D [IC Latch-Up Test].
(11) For tape and reel the storage temperature range is [–10°C; +50°C] with a maximum relative humidity of 70%. TI recommends returning
to ambient room temperature before usage.
Fail-safe I/O terminals are designed such they do not have dependencies on the respective I/O power supply voltage. This allows
external voltage sources to be connected to these I/O terminals when the respective I/O power supplies are turned off. The USB0_VBUS
and USB1_VBUS are the only fail-safe I/O terminals. All other I/O terminals are not fail-safe and the voltage applied to them should be
limited to the value defined by the steady state max. Voltage at all I/O pins parameter in Section 5.1.

5.8 Thermal Resistance Characteristics for ZCE and ZCZ Packages
Failure to maintain a junction temperature within the range specified in Section 5.5 reduces operating
lifetime, reliability, and performance—and may cause irreversible damage to the system. Therefore, the
product design cycle should include thermal analysis to verify the maximum operating junction
temperature of the device. It is important this thermal analysis is performed using specific system use
cases and conditions. TI provides an application report to aid users in overcoming some of the existing
challenges of producing a good thermal design. For more information, see AM335x Thermal
Considerations.

5.9 External Capacitors
To improve module performance, decoupling capacitors are required to suppress the switching noise
generated by high frequency and to stabilize the supply voltage. A decoupling capacitor is most effective
when it is close to the device, because this minimizes the inductance of the circuit board wiring and
interconnects.
5.9.1 Voltage Decoupling Capacitors
Table 5-13 summarizes the Core voltage decoupling characteristics.
5.9.1.1 Core Voltage Decoupling Capacitors

A. RTC_PWRONRSTn should be asserted for at least 1 ms to provide enough time for the internal RTC LDO output to
reach a valid level before RTC reset is released.
B. When using the ZCZ package option, VDD_MPU and VDD_CORE power inputs may be powered from the same
source if the application only uses operating performance points (OPPs) that define a common power supply voltage
for VDD_MPU and VDD_CORE. The ZCE package option has the VDD_MPU domain merged with the VDD_CORE
domain.
C. If a USB port is not used, the respective VDDA1P8V_USB terminal may be connected to any 1.8-V power supply and
the respective VDDA3P3V_USB terminal may be connected to any 3.3-V power supply. If the system does not have a
3.3-V power supply, the VDDA3P3V_USB terminal may be connected to ground.
D. If the system uses mDDR or DDR2 memory devices, VDDS_DDR can be ramped simultaneously with the other 1.8-V
I/O power supplies.
E. VDDS_RTC can be ramped independent of other power supplies if PMIC_POWER_EN functionality is not required. If
VDDS_RTC is ramped after VDD_CORE, there might be a small amount of additional leakage current on
VDD_CORE. The power sequence shown provides the lowest leakage option.
F. To configure VDDSHVx [1-6] as 1.8 V, power up the respective VDDSHVx [1-6] to 1.8 V following the recommended
sequence. To configure VDDSHVx [1-6] as 3.3 V, power up the respective VDDSHVx [1-6] to 3.3 V following the
recommended sequence.

6.1.2 Power-Down Sequencing
PWRONRSTn input terminal should be taken low, which stops all internal clocks before power supplies
are turned off. All other external clocks to the device should be shut off.
The preferred way to sequence power down is to have all the power supplies ramped down sequentially in
the exact reverse order of the power-up sequencing. In other words, the power supply that has been
ramped up first should be the last one that should be ramped down. This ensures there would be no
spurious current paths during the power-down sequence. The VDDS power supply must ramp down after
all 3.3-V VDDSHVx [1-6] power supplies.
If it is desired to ramp down VDDS and VDDSHVx [1-6] simultaneously, it should always be ensured that
the difference between VDDS and VDDSHVx [1-6] during the entire power-down sequence is <2 V. Any
violation of this could cause reliability risks for the device. TI recommends maintaining VDDS 1.5V as all
the other supplies fully ramp down to minimize in-rush currents.

If none of the VDDSHVx [1-6] power supplies are configured as 3.3 V, the VDDS power supply may ramp

6.2 Clock Specifications
6.2.1 Input Clock Specifications
The AM335x device has two clock inputs. Each clock input passes through an internal oscillator which can
be connected to an external crystal circuit (oscillator mode) or external LVCMOS square-wave digital clock
source (bypass mode). The oscillators automatically operate in bypass mode when their input is
connected to an external LVCMOS square-wave digital clock source. The oscillator associated with a
specific clock input must be enabled when the clock input is being used in either oscillator mode or bypass
mode.
The OSC1 oscillator provides a 32.768-kHz reference clock to the real-time clock (RTC) and is connected
to the RTC_XTALIN and RTC_XTALOUT terminals. This clock source is referred to as the 32K oscillator
(CLK_32K_RTC) in the AM335x and AMIC110 Sitara Processors Technical Reference Manual. OSC1 is
disabled by default after power is applied. This clock input is optional and may not be required if the RTC
is configured to receive a clock from the internal 32k RC oscillator (CLK_RC32K) or peripheral PLL
(CLK_32KHZ) which receives a reference clock from the OSC0 input.
The OSC0 oscillator provides a 19.2-MHz, 24-MHz, 25-MHz, or 26-MHz reference clock which is used to
clock all non-RTC functions and is connected to the XTALIN and XTALOUT terminals. This clock source is
referred to as the master oscillator (CLK_M_OSC) in the AM335x and AMIC110 Sitara Processors
Technical Reference Manual. OSC0 is enabled by default after power is applied.
For more information related to recommended circuit topologies and crystal oscillator circuit requirements
for these clock inputs, see Section 6.2.2.
6.2.2 Input Clock Requirements
6.2.2.1 OSC0 Internal Oscillator Clock Source
Figure 6-9 shows the recommended crystal circuit. TI recommends that preproduction printed-circuit board
(PCB) designs include the two optional resistors Rbias and Rdin case they are required for proper oscillator
operation when combined with production crystal circuit components. In most cases, Rbias is not required
and Rdis a 0-Ωresistor. These resistors may be removed from production PCB designs after evaluating
oscillator performance with production crystal circuit components installed on preproduction PCBs.
The XTALIN terminal has a 15- to 40-kΩinternal pulldown resistor which is enabled when OSC0 is
disabled. This internal resistor prevents the XTALIN terminal from floating to an invalid logic level which
may increase leakage current through the oscillator input buffer.

6.2.2.2 OSC0 LVCMOS Digital Clock Source
Figure 6-11 shows the recommended oscillator connections when OSC0 is connected to an LVCMOS
square-wave digital clock source. The LVCMOS clock source is connected to the XTALIN terminal. The
ground for the LVCMOS clock source and VSS_OSC should be connected directly to the nearest PCB
digital ground (VSS). In this mode of operation, the XTALOUT terminal should not be used to source any
external components. The PCB design should provide a mechanism to disconnect the XTALOUT terminal
from any external components or signal traces that may couple noise into OSC0 via the XTALOUT
terminal.
The XTALIN terminal has a 15- to 40-kΩinternal pulldown resistor which is enabled when OSC0 is
disabled. This internal resistor prevents the XTALIN terminal from floating to an invalid logic level which
may increase leakage current through the oscillator input buffer.

6.2.2.4 OSC1 LVCMOS Digital Clock Source
Figure 6-15 shows the recommended oscillator connections when OSC1 of the ZCE package is connected
to an LVCMOS square-wave digital clock source and Figure 6-16 shows the recommended oscillator
connections when OSC1 of the ZCZ package is connected to an LVCMOS square-wave digital clock
source. The LVCMOS clock source is connected to the RTC_XTALIN terminal. The ground for the
LVCMOS clock source and VSS_RTC of the ZCZ package should be connected directly to the nearest
PCB digital ground (VSS). In this mode of operation, the RTC_XTALOUT terminal should not be used to
source any external components. The PCB design should provide a mechanism to disconnect the
RTC_XTALOUT terminal from any external components or signal traces that may couple noise into OSC1
through the RTC_XTALOUT terminal.
The RTC_XTALIN terminal has a 10- to 40-kΩinternal pullup resistor which is enabled when OSC1 is
disabled. This internal resistor prevents the RTC_XTALIN terminal from floating to an invalid logic level
which may increase leakage current through the oscillator input buffer.

6.2.2.5 OSC1 Not Used
Figure 6-17 shows the recommended oscillator connections when OSC1 of the ZCE package is not used
and Figure 6-18 shows the recommended oscillator connections when OSC1 of the ZCZ package is not
used. An internal 10-kΩpullup on the RTC_XTALIN terminal is turned on when OSC1 is disabled to
prevent this input from floating to an invalid logic level which may increase leakage current through the
oscillator input buffer. OSC1 is disabled by default after power is applied. Therefore, both RTC_XTALIN
and RTC_XTALOUT terminals should be a no connect (NC) when OSC1 is not used.

6.2.3 Output Clock Specifications
The AM335x device has two clock output signals. The CLKOUT1 signal is always a replica of the OSC0
input clock which is referred to as the master oscillator (CLK_M_OSC) in the AM335x and AMIC110 Sitara
Processors Technical Reference Manual. The CLKOUT2 signal can be configured to output the OSC1
input clock, which is referred to as the 32K oscillator (CLK_32K_RTC) in the AM335x and AMIC110 Sitara
Processors Technical Reference Manual, or four other internal clocks. For more information related to
configuring these clock output signals, see the CLKOUT Signals section of the AM335x and AMIC110
Sitara Processors Technical Reference Manual.
6.2.4 Output Clock Characteristics
NOTE
The AM335x CLKOUT1 and CLKOUT2 clock outputs should not be used as a synchronous
clock for any of the peripheral interfaces because they were not timing closed to any other
signals. These clock outputs also were not designed to source any time critical external
circuits that require a low jitter reference clock. The jitter performance of these outputs is
unpredictable due to complex combinations of many system variables. For example,
CLKOUT2 may be sourced from several PLLs with each PLL supporting many configurations
that yield different jitter performance. There are also other unpredictable contributors to jitter
performance such as application specific noise or crosstalk into the clock circuits. Therefore,
there are no plans to specify jitter performance for these outputs.
6.2.4.1 CLKOUT1
The CLKOUT1 signal can be output on the XDMA_EVENT_INTR0 terminal. This terminal connects to one
of seven internal signals via configurable multiplexers. The XDMA_EVENT_INTR0 multiplexer must be
configured for Mode 3 to connect the CLKOUT1 signal to the XDMA_EVENT_INTR0 terminal.
The default reset configuration of the XDMA_EVENT_INTR0 multiplexer is selected by the logic level
applied to the LCD_DATA5 terminal on the rising edge of PWRONRSTn. The XDMA_EVENT_INTR0
multiplexer is configured to Mode 7 if the LCD_DATA5 terminal is low on the rising edge of PWRONRSTn
or Mode 3 if the LCD_DATA5 terminal is high on the rising edge of PWRONRSTn. This allows the
CLKOUT1 signal to be output on the XDMA_EVENT_INTR0 terminal without software intervention. In this
mode, the output is held low while PWRONRSTn is active and begins to toggle after PWRONRSTn is
released.
6.2.4.2 CLKOUT2
The CLKOUT2 signal can be output on the XDMA_EVENT_INTR1 terminal. This terminal connects to one
of seven internal signals via configurable multiplexers. The XDMA_EVENT_INTR1 multiplexer must be
configured for Mode 3 to connect the CLKOUT2 signal to the XDMA_EVENT_INTR1 terminal.
The default reset configuration of the XDMA_EVENT_INTR1 multiplexer is always Mode 7. Software must
configure the XDMA_EVENT_INTR1 multiplexer to Mode 3 for the CLKOUT2 signal to be output on the
XDMA_EVENT_INTR1 terminal.

Peripheral Information and TimingsCopyright © 2011–2016, Texas Instruments Incorporated
7 Peripheral Information and Timings
The AM335x device contains many peripheral interfaces. In order to reduce package size and lower
overall system cost while maintaining maximum functionality, many of the AM335x terminals can multiplex
up to eight signal functions. Although there are many combinations of pin multiplexing that are possible,
only a certain number of sets, called I/O Sets, are valid due to timing limitations. These valid I/O Sets were
carefully chosen to provide many possible application scenarios for the user.
Texas Instruments has developed a Windows-based application called Pin Mux Utility that helps a system
designer select the appropriate pin-multiplexing configuration for their AM335x-based product design. The
Pin Mux Utility provides a way to select valid I/O Sets of specific peripheral interfaces to ensure the pin-
multiplexing configuration selected for a design only uses valid I/O Sets supported by the AM335x device.
7.1 Parameter Information
The data provided in the following Timing Requirements and Switching Characteristics tables assumes the
device is operating within the Recommended Operating Conditions defined in Section 5, unless otherwise
noted.
7.1.1 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routings. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing or decreasing such delays. TI recommends using the available I/O buffer
information specification (IBIS) models to analyze the timing characteristics correctly. If needed, external
logic hardware such as buffers may be used to compensate any timing differences.
The timing parameter values specified in this data manual assume the SLEWCTRL bit in each pad control
register is configured for fast mode (0b).
For the mDDR(LPDDR), DDR2, DDR3, DDR3L memory interface, it is not necessary to use the IBIS
models to analyze timing characteristics. TI provides a PCB routing rules solution that describes the
routing rules to ensure the mDDR(LPDDR), DDR2, DDR3, DDR3L memory interface timings are met.
7.2 Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner.
7.3 OPP50 Support
Some peripherals and features have limited support when the device is operating in OPP50. A complete
list of these limitations follows.

7.6 Ethernet Media Access Controller (EMAC) and Switch
7.6.1 EMAC and Switch Electrical Data and Timing
The EMAC and Switch implemented in the AM335x device supports GMII mode, but the AM335x design
does not pin out 9 of the 24 GMII signals. This was done to reduce the total number of package terminals.
Therefore, the AM335x device does not support GMII mode. MII mode is supported with the remaining
GMII signals.
The AM335x and AMIC110 Sitara Processors Technical Reference Manual and this document may
reference internal signal names when discussing peripheral input and output signals because many of the
AM335x package terminals can be multiplexed to one of several peripheral signals. For example, the
AM335x terminal names for port 1 of the EMAC and switch have been changed from GMII to MII to
indicate their Mode 0 function, but the internal signal is named GMII. However, documents that describe
the Ethernet switch reference these signals by their internal signal name. For a cross-reference of internal
signal names to terminal names, see Table 4-2.
Operation of the EMAC and switch is not supported for OPP50.

A. RGMII[x]_RCLK must be externally delayed relative to the RGMII[x]_RD[3:0] and RGMII[x]_RCTL signals to meet the
respective timing requirements.
B. Data and control information is received using both edges of the clocks. RGMII[x]_RD[3:0] carries data bits 3-0 on the
rising edge of RGMII[x]_RCLK and data bits 7-4 on the falling edge of RGMII[x]_RCLK. Similarly, RGMII[x]_RCTL
carries RXDV on rising edge of RGMII[x]_RCLK and RXERR on falling edge of RGMII[x]_RCLK.

A. The EMAC and switch implemented in the AM335x device supports internal delay mode, but timing closure was not
performed for this mode of operation. Therefore, the AM335x device does not support internal delay mode.
B. Data and control information is transmitted using both edges of the clocks. RGMII[x]_TD[3:0] carries data bits 3-0 on
the rising edge of RGMII[x]_TCLK and data bits 7-4 on the falling edge of RGMII[x]_TCLK. Similarly, RGMII[x]_TCTL
carries TXEN on rising edge of RGMII[x]_TCLK and TXERR of falling edge of RGMII[x]_TCLK.

7.7.2 mDDR(LPDDR), DDR2, DDR3, DDR3L Memory Interface
The device has a dedicated interface to mDDR(LPDDR), DDR2, DDR3, and DDR3L SDRAM. It supports
JEDEC standard compliant mDDR(LPDDR), DDR2, DDR3, and DDR3L SDRAM devices with a 16-bit
data path to external SDRAM memory.
For more details on the mDDR(LPDDR), DDR2, DDR3, and DDR3L memory interface, see the EMIF
section of the AM335x and AMIC110 Sitara Processors Technical Reference Manual.
7.7.2.1 mDDR (LPDDR) Routing Guidelines
It is common to find industry references to mobile double data rate (mDDR) when discussing JEDEC
defined low-power double-data rate (LPDDR) memory devices. The following guidelines use LPDDR when
referencing JEDEC defined low-power double-data rate memory devices.
7.7.2.1.1 Board Designs
TI only supports board designs that follow the guidelines outlined in this document. The switching
characteristics and the timing diagram for the LPDDR memory interface are shown in Table 7-31 and
Figure 7-32.

1tc(DDR_CK)
tc(DDR_CKn) Cycle time, DDR_CK and DDR_CKn 5 (1) ns
(1) The JEDEC JESD209B specification only defines the maximum clock period for LPDDR333 and faster speed bin LPDDR memory
devices. To determine the maximum clock period, see the respective LPDDR memory data sheet.
Figure 7-32. LPDDR Memory Interface Clock Timing
7.7.2.1.2 LPDDR Interface
This section provides the timing specification for the LPDDR interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. These rules, when followed, result in a reliable LPDDR memory system without the
need for a complex timing closure process. For more information regarding the guidelines for using this
LPDDR specification, see Understanding TI’s PCB Routing Rule-Based DDR Timing Specification. This
application report provides generic guidelines and approach. All the specifications provided in the data
manual take precedence over the generic guidelines and must be adhered to for a reliable LPDDR
interface operation.
7.7.2.1.2.1 LPDDR Interface Schematic
Figure 7-33 shows the schematic connections for 16-bit interface on the AM335x device using one x16
LPDDR device. The AM335x LPDDR memory interface only supports 16-bit-wide mode of operation. The
AM335x device can only source one load connected to the DQS[x] and DQ[x] net class signals and one
load connected to the CK and ADDR_CTRL net class signals. For more information related to net classes,
see Section 7.7.2.1.2.8.

7.7.2.1.2.2 Compatible JEDEC LPDDR Devices
Table 7-32 shows the parameters of the JEDEC LPDDR devices that are compatible with this interface.
Generally, the LPDDR interface is compatible with x16 LPDDR400 speed grade LPDDR devices.
Table 7-32. Compatible JEDEC LPDDR Devices (Per Interface)(1)
NO. PARAMETER MIN MAX UNIT
1 JEDEC LPDDR device speed grade LPDDR400

3 JEDEC LPDDR device count 1 Devices
4 JEDEC LPDDR device terminal count 60 Terminals
(1) If the LPDDR interface is operated with a clock frequency less than 200 MHz, lower-speed grade LPDDR devices may be used if the
minimum clock period specified for the LPDDR device is less than or equal to the minimum clock period selected for the AM335x
LPDDR interface.
7.7.2.1.2.3 PCB Stackup
The minimum stackup required for routing the AM335x device is a 4-layer stackup as shown in Table 7-
33. Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance signal
integrity and electromagnetic interference performance, or to reduce the size of the PCB footprint.
Table 7-33. Minimum PCB Stackup(1)
LAYER TYPE DESCRIPTION
1 Signal Top signal routing
2 Plane Ground
3 Plane Split Power Plane
4 Signal Bottom signal routing
(1) All signals that have critical signal integrity requirements should be routed first on layer 1. It may not be possible to route all of these
signals on layer 1, therefore requiring routing of some signals on layer 4. When this is done, the signal routes on layer 4 must not cross
splits in the power plane.

Figure 7-34 shows the required placement for the LPDDR devices. The dimensions for this figure are
defined in Table 7-35. The placement does not restrict the side of the PCB on which the devices are

7.7.2.1.2.5 LPDDR Keepout Region
The region of the PCB used for the LPDDR circuitry must be isolated from other signals. The LPDDR
keepout region is defined for this purpose and is shown in Figure 7-35. This region should encompass all
LPDDR circuitry and the region size varies with component placement and LPDDR routing. Additional
clearances required for the keepout region are shown in Table 7-35. Non-LPDDR signals must not be
routed on the same signal layer as LPDDR signals within the LPDDR keepout region. Non-LPDDR signals
may be routed in the region provided they are routed on layers separated from LPDDR signal layers by a
ground layer. No breaks should be allowed in the reference ground or VDDS_DDR power plane in this
region. In addition, the VDDS_DDR power plane should cover the entire keepout region.

7.7.2.1.2.6 Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the LPDDR and other circuitry.
Table 7-36 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note

7.7.2.1.2.7 High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critical for proper LPDDR interface operation. It is particularly

7.7.2.1.2.9 LPDDR Signal Termination
There is no specific need for adding terminations on the LPDDR interface. However, system designers
may evaluate the need for serial terminators for EMI and overshoot reduction. Placement of serial
terminations for DQS[x] and DQ[x] net class signals should be determined based on PCB analysis.
Placement of serial terminations for ADDR_CTRL net class signals should be close to the AM335x device.
Table 7-40 shows the specifications for the serial terminators in such cases.

(1) Only series termination is permitted.
(2) Zo is the LPDDR PCB trace characteristic impedance.
(3) Series termination values larger than typical only recommended to address EMI issues.
(4) Series termination values should be uniform across net class.

7.7.2.2 DDR2 Routing Guidelines
7.7.2.2.1 Board Designs
TI only supports board designs that follow the guidelines outlined in this document. Table 7-43 and
Figure 7-38 show the switching characteristics and timing diagram for the DDR2 memory interface.
Table 7-43. Switching Characteristics for DDR2 Memory Interface
NO. PARAMETER MIN MAX UNIT
1tc(DDR_CK)
tc(DDR_CKn) Cycle time, DDR_CK and DDR_CKn 3.75 8(1) ns
(1) The JEDEC JESD79-2F specification defines the maximum clock period of 8 ns for all standard-speed bin DDR2 memory devices.
Therefore, all standard-speed bin DDR2 memory devices are required to operate at 125 MHz.
Figure 7-38. DDR2 Memory Interface Clock Timing
7.7.2.2.2 DDR2 Interface
This section provides the timing specification for the DDR2 interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. These rules, when followed, result in a reliable DDR2 memory system without the need
for a complex timing closure process. For more information regarding the guidelines for using this DDR2
specification, see Understanding TI’s PCB Routing Rule-Based DDR Timing Specification. This application
report provides generic guidelines and approach. All the specifications provided in the data manual take
precedence over the generic guidelines and must be adhered to for a reliable DDR2 interface operation.
7.7.2.2.2.1 DDR2 Interface Schematic
Figure 7-39 shows the schematic connections for 16-bit interface on the AM335x device using one x16
DDR2 device and Figure 7-40 shows the schematic connections for 16-bit interface on the AM335x device
using two x8 DDR2 devices. The AM335x DDR2 memory interface only supports 16-bit-wide mode of
operation. The AM335x device can only source one load connected to the DQS[x] and DQ[x] net class
signals and two loads connected to the CK and ADDR_CTRL net class signals. For more information
related to net classes, see Section 7.7.2.2.2.8.

7.7.2.2.2.2 Compatible JEDEC DDR2 Devices
Table 7-44 shows the parameters of the JEDEC DDR2 devices that are compatible with this interface.
Generally, the DDR2 interface is compatible with x16 or x8 DDR2-533 speed grade DDR2 devices.
Table 7-44. Compatible JEDEC DDR2 Devices (Per Interface)(1)
NO. PARAMETER MIN MAX UNIT
1 JEDEC DDR2 device speed grade(2) DDR2-533
2 JEDEC DDR2 device bit width x8 x16 bits
3 JEDEC DDR2 device count 1 2 devices
4 JEDEC DDR2 device terminal count(3) 60 84 terminals
(1) If the DDR2 interface is operated with a clock frequency less than 266 MHz, lower-speed grade DDR2 devices may be used if the
minimum clock period specified for the DDR2 device is less than or equal to the minimum clock period selected for the AM335x DDR2
interface.
(2) Higher DDR2 speed grades are supported due to inherent JEDEC DDR2 backward compatibility.
(3) 92-terminal devices are also supported for legacy reasons. New designs will migrate to 84-terminal DDR2 devices. Electrically, the 92-
and 84-terminal DDR2 devices are the same.
7.7.2.2.2.3 PCB Stackup
The minimum stackup required for routing the AM335x device is a 4-layer stackup as shown in Table 7-
45. Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance signal
integrity and electromagnetic interference performance, or to reduce the size of the PCB footprint.
Table 7-45. Minimum PCB Stackup(1)
LAYER TYPE DESCRIPTION
1 Signal Top signal routing
2 Plane Ground
3 Plane Split power plane
4 Signal Bottom signal routing
(1) All signals that have critical signal integrity requirements should be routed first on layer 1. It may not be possible to route all of these
signals on layer 1, therefore requiring routing of some signals on layer 4. When this is done, the signal routes on layer 4 must not cross
splits in the power plane.

7.7.2.2.2.5 DDR2 Keepout Region
The region of the PCB used for the DDR2 circuitry must be isolated from other signals. The DDR2
keepout region is defined for this purpose and is shown in Figure 7-42. This region should encompass all
DDR2 circuitry and the region size varies with component placement and DDR2 routing. Additional
clearances required for the keepout region are shown in Table 7-47. Non-DDR2 signals must not be
routed on the same signal layer as DDR2 signals within the DDR2 keepout region. Non-DDR2 signals
may be routed in the region provided they are routed on layers separated from DDR2 signal layers by a
ground layer. No breaks should be allowed in the reference ground or VDDS_DDR power plane in this
region. In addition, the VDDS_DDR power plane should cover the entire keepout region.

7.7.2.2.2.6 Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR2 and other circuitry.
Table 7-48 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the AM335x DDR2 interface and DDR2 devices. Additional
bulk bypass capacitance may be needed for other circuitry.

7.7.2.2.2.9 DDR2 Signal Termination
Signal terminations are required on the CK and ADDR_CTRL net class signals. Serial terminations should
be used on the CK and ADDR_CTRL lines and is the preferred termination scheme. On-device
terminations (ODTs) are required on the DQS[x] and DQ[x] net class signals. They should be enabled to
ensure signal integrity. Table 7-52 shows the specifications for the series terminators. Placement of serial
terminations for ADDR_CTRL net class signals should be close to the AM335x device.

NO. PARAMETER MIN TYP MAX UNIT
1 CK net class(1) 0 10 Ω
2 ADDR_CTRL net class(1)(2)(3) 0 22 Zo(4) Ω
3 DQS0, DQS1, DQ0, and DQ1 net classes(5) N/A N/A Ω
(1) Only series termination is permitted.
(2) Series termination values larger than typical only recommended to address EMI issues.
(3) Series termination values should be uniform across net class.
(4) Zo is the DDR2 PCB trace characteristic impedance.
(5) No external termination resistors are allowed and ODT must be used for these net classes.
If the DDR2 interface is operated at a lower frequency (<200-MHz clock rate), on-device terminations are
not specifically required for the DQS[x] and DQ[x] net class signals and serial terminations for the CK and
ADDR_CTRL net class signals are not mandatory. System designers may evaluate the need for serial
terminators for EMI and overshoot reduction. Placement of serial terminations for DQS[x] and DQ[x] net
class signals should be determined based on PCB analysis. Placement of serial terminations for
ADDR_CTRL net class signals should be close to the AM335x device. Table 7-53 shows the
specifications for the serial terminators in such cases.

7.7.2.2.2.10 DDR_VREF Routing
DDR_VREF is used as a reference by the input buffers of the DDR2 memories as well as the AM335x
device. DDR_VREF is intended to be half the DDR2 power supply voltage and should be created using a
resistive divider as shown in Figure 7-39 and Figure 7-40. TI does not recommend other methods of
creating DDR_VREF. Figure 7-43 shows the layout guidelines for DDR_VREF.

7.7.2.2.3 DDR2 CK and ADDR_CTRL Routing
Figure 7-44 shows the topology of the routing for the CK and ADDR_CTRL net classes. The length of
signal path AB and AC should be minimized with emphasis to minimize lengths C and D such that length

7.7.2.3 DDR3 and DDR3L Routing Guidelines
NOTE
All references to DDR3 in this section apply to DDR3 and DDR3L devices, unless otherwise
noted.
7.7.2.3.1 Board Designs
TI only supports board designs using DDR3 memory that follow the guidelines in this document. The
switching characteristics and timing diagram for the DDR3 memory interface are shown in Table 7-56 and
Figure 7-46.
Table 7-56. Switching Characteristics for DDR3 Memory Interface
NO. PARAMETER MIN MAX UNIT
1tc(DDR_CK)
tc(DDR_CKn) Cycle time, DDR_CK and DDR_CKn 2.5 3.3(1) ns
(1) Two DDR3 devices are mirrored when one device is placed on the top of the board and the second device is placed on the bottom of
the board.
(1) The JEDEC JESD79-3F Standard defines the maximum clock period of 3.3 ns for all standard-speed bin DDR3 and DDR3L memory
devices. Therefore, all standard-speed bin DDR3 and DDR3L memory devices are required to operate at 303 MHz.
Figure 7-46. DDR3 Memory Interface Clock Timing
7.7.2.3.1.1 DDR3 versus DDR2
This specification only covers AM335x PCB designs that use DDR3 memory. Designs using DDR2
memory should use the DDR2 routing guidleines described in Section 7.7.2.2. While similar, the two
memory systems have different requirements. It is currently not possible to design one PCB that meets
the requirements of both DDR2 and DDR3.
7.7.2.3.2 DDR3 Device Combinations
Because there are several possible combinations of device counts and single-side or dual-side mounting,
Table 7-57 summarizes the supported device configurations.
Table 7-57. Supported DDR3 Device Combinations
NUMBER OF DDR3 DEVICES DDR3 DEVICE WIDTH (BITS) MIRRORED? DDR3 EMIF WIDTH (BITS)
1 16 N 16
2 8 Y(1) 16
7.7.2.3.3 DDR3 Interface
This section provides the timing specification for the DDR3 interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. These rules, when followed, result in a reliable DDR3 memory system without the need
for a complex timing closure process. For more information regarding the guidelines for using this DDR3
specification, see Understanding TI's PCB Routing Rule-Based DDR Timing Specification. This application
report provides generic guidelines and approach. All the specifications provided in the data manual take
precedence over the generic guidelines and must be adhered to for a reliable DDR3 interface operation.

7.7.2.3.3.1 DDR3 Interface Schematic
The DDR3 interface schematic varies, depending upon the width of the DDR3 devices used. Figure 7-47
shows the schematic connections for 16-bit interface on the AM335x device using one x16 DDR3 device
and Figure 7-49 shows the schematic connections for 16-bit interface on the AM335x device using two x8
DDR3 devices. The AM335x DDR3 memory interface only supports 16-bit wide mode of operation. The
AM335x device can only source one load connected to the DQS[x] and DQ[x] net class signals and two
loads connected to the CK and ADDR_CTRL net class signals. For more information related to net
classes, see Section 7.7.2.3.3.8.

7.7.2.3.3.3 PCB Stackup
The minimum stackup for routing the DDR3 interface is a four-layer stack up as shown in Table 7-59.
Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance signal
integrity and electromagnetic interference performance, or to reduce the size of the PCB footprint.
Table 7-59. Minimum PCB Stackup(1)
LAYER TYPE DESCRIPTION
1 Signal Top signal routing
2 Plane Ground
3 Plane Split Power Plane
4 Signal Bottom signal routing
(1) All signals that have critical signal integrity requirements should be routed first on layer 1. It may not be possible to route all of these
signals on layer 1, therefore requiring routing of some signals on layer 4. When this is done, the signal routes on layer 4 must not cross
splits in the power plane.

(2) Ground reference layers are preferred over power reference layers. Be sure to include bypass capacitors to accommodate reference
layer return current as the trace routes switch routing layers.
(3) No traces should cross reference plane cuts within the DDR3 routing region. High-speed signal traces crossing reference plane cuts
create large return current paths which can lead to excessive crosstalk and EMI radiation.
(4) Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
(5) An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available
for power routing. An 18-mil pad is required for minimum layer count escape.
(6) Zo is the nominal singled-ended impedance selected for the PCB.
(7) This parameter specifies the AC characteristic impedance tolerance for each segment of a PCB signal trace relative to the chosen Zo
defined by the single-ended impedance parameter.

7.7.2.3.3.5 DDR3 Keepout Region
The region of the PCB used for DDR3 circuitry must be isolated from other signals. The DDR3 keepout
region is defined for this purpose and is shown in Figure 7-51. This region should encompass all DDR3
circuitry and the region size varies with component placement and DDR3 routing. Additional clearances
required for the keepout region are shown in Table 7-61. Non-DDR3 signals must not be routed on the
same signal layer as DDR3 signals within the DDR3 keepout region. Non-DDR3 signals may be routed in
the region provided they are routed on layers separated from DDR3 signal layers by a ground layer. No
breaks should be allowed in the reference ground or VDDS_DDR power plane in this region. In addition,
the VDDS_DDR power plane should cover the entire keepout region.

7.7.2.3.3.6 Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR3 and other circuitry.
Table 7-62 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the AM335x DDR3 interface and DDR3 devices. Additional
bulk bypass capacitance may be needed for other circuitry.

7.7.2.3.3.7 High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critical for proper DDR3 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, the AM335x device
DDR3 power, and the AM335x device DDR3 ground connections. Table 7-63 contains the specification for
the HS bypass capacitors as well as for the power connections on the PCB. Generally speaking, it is good
to:
Fit as many HS bypass capacitors as possible.
Minimize the distance from the bypass capacitor to the power terminals being bypassed.
Use the smallest physical sized capacitors possible with the highest capacitance readily available.
Connect the bypass capacitor pads to their vias using the widest traces possible and using the largest
hole size via possible.
Minimize via sharing. Note the limits on via sharing shown in Table 7-63.

(6) Per DDR3 device.
(7) An additional HS bypass capacitor can share the connection vias only if it is mounted on the opposite side of the board. No sharing of
vias is permitted on the same side of the board.
(8) An HS bypass capacitor may share a via with a DDR3 device mounted on the same side of the PCB. A wide trace should be used for
the connection and the length from the capacitor pad to the DDR3 device pad should be less than 150 mils.
(9) Up to two pairs of DDR3 power and ground terminals may share a via.
7.7.2.3.3.7.1 Return Current Bypass Capacitors
Use additional bypass capacitors if the return current reference plane changes due to DDR3 signals
hopping from one signal layer to another. The bypass capacitor here provides a path for the return current
to hop planes along with the signal. As many of these return current bypass capacitors should be used as
possible. Because these are returns for signal current, the signal via size may be used for these
capacitors.

Table 7-64 lists the clock net classes for the DDR3 interface. Table 7-65 lists the signal net classes, and
associated clock net classes, for signals in the DDR3 interface. These net classes are used for the
termination and routing rules that follow.

7.7.2.3.3.9 DDR3 Signal Termination
Signal terminations are required for the CK and ADDR_CTRL net class signals. On-device terminations
(ODTs) are required on the DQS[x] and DQ[x] net class signals. Detailed termination specifications are
covered in the routing rules in the following sections.
Figure 7-48 provides an example DDR3 schematic with a single 16-bit DDR3 memory device that does
not have VTT termination on the address and control signals. A typical DDR3 point-to-point topology may
provide acceptable signal integrity without VTT termination. System performance should be verified by
performing signal integrity analysis using specific PCB design details before implementing this topology.
7.7.2.3.3.10 DDR_VREF Routing
DDR_VREF is used as a reference by the input buffers of the DDR3 memories as well as the AM335x
device. DDR_VREF is intended to be half the DDR3 power supply voltage and is typically generated with
a voltage divider connected to the VDDS_DDR power supply. It should be routed as a nominal 20-mil wide
trace with 0.1 µF bypass capacitors near each device connection. Narrowing of DDR_VREF is allowed to
accommodate routing congestion.
7.7.2.3.3.11 VTT
Like DDR_VREF, the nominal value of the VTT supply is half the DDR3 supply voltage. Unlike
DDR_VREF, VTT is expected to source and sink current, specifically the termination current for the
ADDR_CTRL net class Thevinen terminators. VTT is needed at the end of the address bus and it should
be routed as a power sub-plane. VTT should be bypassed near the terminator resistors.
7.7.2.3.4 DDR3 CK and ADDR_CTRL Topologies and Routing Definition
The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew
between them. CK is a bit more complicated because it runs at a higher transition rate and is differential.
The following subsections show the topology and routing for various DDR3 configurations for CK and
ADDR_CTRL. The figures in the following subsections define the terms for the routing specification
detailed in Table 7-66.

7.7.2.3.6 Routing Specification
7.7.2.3.6.1 CK and ADDR_CTRL Routing Specification
Skew within the CK and ADDR_CTRL net classes directly reduces setup and hold margin and, thus, this
skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter
traces up to the length of the longest net in the net class and its associated clock. A metric to establish
this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the
length between the points when connecting them only with horizontal or vertical segments. A reasonable
trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address
Control Longest Manhattan distance.
Given the clock and address pin locations on the AM335x device and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 7-66 shows this distance for
two loads. The specifications on the lengths of the transmission lines for the address bus are determined
from this distance. CACLM is determined similarly for other address bus configurations; that is, it is based
on the longest net of the CK and ADDR_CTRL net class. For CK and ADDR_CTRL routing, these
specifications are contained in Table 7-66.
A. It is very likely that the longest CK and ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the
DDR3 memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net
class that satisfies this criteria and use as the baseline for CK and ADDR_CTRL skew matching and length control.
The length of shorter CK and ADDR_CTRL stubs as well as the length of the terminator stub are not included in this
length calculation. Nonincluded lengths are grayed out in the figure.
Assuming A8 is the longest, CALM = CACLMY + CACLMX + 300 mils.
The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8.

(1) CK represents the clock net class, and ADDR_CTRL represents the address and control signal net class.
(2) The use of vias should be minimized.
(3) Additional bypass capacitors are required when using the VDDS_DDR plane as the reference plane to allow the return current to jump
between the VDDS_DDR plane and the ground plane when the net class switches layers at a via.
(4) Mirrored configuration (one DDR3 device on top of the board and one DDR3 device on the bottom).
(5) Nonmirrored configuration (all DDR3 memories on same side of PCB).
(6) While this length can be increased for convenience, its length should be minimized.
(7) ADDR_CTRL net class only (not CK net class). Minimizing this skew is recommended, but not required.
(8) CK net class only.
(9) CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes + 300 mils. For definition, see Section 7.7.2.3.6.1
and Figure 7-66.
(10) Center-to-center spacing is allowed to fall to minimum (w) for up to 1250 mils of routed length.
(11) Signals from one DQ net class should be considered other DDR3 traces to another DQ net class.
(12) CK spacing set to ensure proper differential impedance. Differential impedance should be Zox 2, where Zois the single-ended
impedance defined in Table 7-60.
(13) Source termination (series resistor at driver) is specifically not allowed.
(14) Termination values should be uniform across the net class.
7.7.2.3.6.2 DQS[x] and DQ[x] Routing Specification
Skew within the DQS[x] and DQ[x] net classes directly reduces setup and hold margin and, thus, this skew
must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces
up to the length of the longest net in the net class and its associated clock. DQLMn is defined as DQ
Longest Manhattan distance n, where n is the byte number. For a 16-bit interface, there are two DQLMs,
DQLM0-DQLM1.
NOTE
Matching the lengths across all bytes is not required, nor is it recommended. Length
matching is only required within each byte.
Given the DQS[x] and DQ[x] pin locations on the AM335x device and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 7-67 shows this distance for
a two-load case. It is from this distance that the specifications on the lengths of the transmission lines for
the data bus are determined. For DQS[x] and DQ[x] routing, these specifications are contained in Table 7-
67.

There are two DQLMs, one for each byte (16-bit interface). Each DQLM is the longest Manhattan distance of the byte;

(1) DQS[x] represents the DQS0 and DQS1 clock net classes, and DQ[x] represents the DQ0 and DQ1 signal net classes.
(2) External termination disallowed. Data termination should use built-in ODT functionality.
(3) DQLMn is the longest Manhattan distance of a byte. For definition, see Section 7.7.2.3.6.2 and Figure 7-67.
(4) DQLM0 is the longest Manhattan length for the DQ0 net class.
(5) DQLM1 is the longest Manhattan length for the DQ1 net class.
(6) Length matching is only done within a byte. Length matching across bytes is not required.
(7) Each DQS clock net class is length matched to its associated DQ signal net class.
(8) Center-to-center spacing is allowed to fall to minimum for up to 1250 mils of routed length.
(9) Other DDR3 trace spacing means signals that are not part of the same DQ[x] signal net class.
(10) This applies to spacing within same DQ[x] signal net class.
(11) DQS[x] pair spacing is set to ensure proper differential impedance. Differential impedance should be Zox 2, where Zois the single-
ended impedance defined in Table 7-60.

7.10 LCD Controller (LCDC)
The LCDC consists of two independent controllers, the raster controller and the LCD interface display
driver (LIDD) controller. Each controller operates independently from the other and only one of them is
active at any given time.
The raster controller handles the synchronous LCD interface. It provides timing and data for constant
graphics refresh to a passive display. It supports a wide variety of monochrome and full-color display
types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale and
serializer. Graphics data is processed and stored in frame buffers. A frame buffer is a contiguous
memory block in the system. A built-in DMA engine supplies the graphics data to the raster engine
which, in turn, outputs to the external LCD device.
The LIDD controller supports the asynchronous LCD interface. It provides full-timing programmability of
control signals (CS, WE, OE, ALE) and output data.
The maximum resolution for the LCD controller is 2048 × 2048 pixels. The maximum frame rate is
determined by the image size in combination with the pixel clock rate.

The display format produced in raster mode is shown in Figure 7-81. An entire frame is delivered one line
at a time. The first line delivered starts at data pixel (1, 1) and ends at data pixel (P, 1). The last line
delivered starts at data pixel (1, L) and ends at data pixel (P, L). The beginning of each new frame is
denoted by the activation of I/O signal LCD_VSYNC. The beginning of each new line is denoted by the
activation of I/O signal LCD_HSYNC.

7.11 Multichannel Audio Serial Port (McASP)
The multichannel audio serial port (McASP) functions as a general-purpose audio serial port optimized for
the needs of multichannel audio applications. The McASP is useful for time-division multiplexed (TDM)
stream, Inter-Integrated Sound (I2S) protocols, and inter-component digital audio interface transmission
(DIT).
7.11.1 McASP Device-Specific Information
The device includes two multichannel audio serial port (McASP) interface peripherals (McASP0 and
McASP1). The McASP module consists of a transmit and receive section. These sections can operate
completely independently with different data formats, separate master clocks, bit clocks, and frame syncs
or, alternatively, the transmit and receive sections may be synchronized. The McASP module also
includes shift registers that may be configured to operate as either transmit data or receive data.
The transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM)
synchronous serial format or in a digital audio interface (DIT) format where the bit stream is encoded for
SPDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP peripheral supports
the TDM synchronous serial format.
The McASP module can support one transmit data format (either a TDM format or DIT format) and one
receive format at a time. All transmit shift registers use the same format and all receive shift registers use
the same format; however, the transmit and receive formats need not be the same. Both the transmit and
receive sections of the McASP also support burst mode, which is useful for nonaudio data (for example,
passing control information between two devices).
The McASP peripheral has additional capability for flexible clock generation and error detection/handling,
as well as error management.
The device McASP0 and McASP1 modules have up to four serial data pins each. The McASP FIFO size
is 256 bytes and two DMA and two interrupt requests are supported. Buffers are used transparently to
better manage DMA, which can be leveraged to manage data flow more efficiently.
For more detailed information on and the functionality of the McASP peripheral, see the Multichannel
Audio Serial Port (McASP) section of the AM335x and AMIC110 Sitara Processors Technical Reference
Manual.

8 Device and Documentation Support
8.1 Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix)
(for example, XAM3358AZCE). Texas Instruments recommends two of three possible prefix designators
for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product
development from engineering prototypes (TMDX) through fully qualified production devices and tools
(TMDS).
Device development evolutionary flow:
XExperimental device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
PPrototype device that is not necessarily the final silicon die and may not necessarily meet
final electrical specifications.
null Production version of the silicon die that is fully qualified.
Support tool development evolutionary flow:
TMDX Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS Fully-qualified development-support product.
X and P devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and TMDS development-support tools have been characterized fully, and the quality
and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (X or P) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be
used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, ZCE), the temperature range (for example, blank is the default commercial
temperature range), and the device speed range, in megahertz (for example, 27 is 275 MHz). Figure 8-1
provides a legend for reading the complete device name for any AM335x device.
For orderable part numbers of AM335x devices in the ZCE and ZCZ package types, see the Package
Option Addendum of this document, ti.com, or contact your TI sales representative.
For additional description of the device nomenclature markings on the die, see the AM335x Sitara
Processors Silicon Errata.

9 Mechanical, Packaging, and Orderable Information
9.1 Via Channel
The ZCE package has been specially engineered with Via Channel technology. This allows larger than
normal PCB via and trace sizes and reduced PCB signal layers to be used in a PCB design with the 0.65-
mm pitch package, and substantially reduces PCB costs. It allows PCB routing in only two signal layers
(four layers total) due to the increased layer efficiency of the Via Channel BGA technology.
Via Channel technology implemented on the ZCE package makes it possible to build an AM335x-based
product with a 4-layer PCB, but a 4-layer PCB may not meet system performance goals. Therefore,
system performance using a 4-layer PCB design must be evaluated during product design.
9.2 Packaging Information
The following pages include mechanical packaging and orderable information. This information is the most
current data available for the designated devices. This data is subject to change without notice and

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-
compliance with the terms and provisions of this Notice.
