PRODUCT DESCRIPTION

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 are 64K x8, 128K x8, 256K x8 and 5124K x8

CMOS Multi-Purpose Flash (MPF) manufactured with

SST’s proprietary, high performance CMOS SuperFlash

technology. The split-gate cell design and thick-oxide tun-

neling injector attain better reliability and manufacturability

compared with alternate approaches. The SST39LF512/

010/020/040 devices write (Program or Erase) with a 3.0-

3.6V power supply. The SST39VF512/010/020/040

devices write with a 2.7-3.6V power supply. The devices

conform to JEDEC standard pinouts for x8 memories.

Featuring high performance Byte-Program, the

SST39LF512/010/020/040 and SST39VF512/010/020/

040 devices provide a maximum Byte-Program time of 20

µsec. These devices use Toggle Bit or Data# Polling to indi-

cate the completion of Program operation. To protect

against inadvertent write, they have on-chip hardware and

Software Data Protection schemes. Designed, manufac-

tured, and tested for a wide spectrum of applications, they

are offered with a guaranteed typical endurance of 10,000

cycles. Data retention is rated at greater than 100 years.

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 devices are suited for applications that require

convenient and economical updating of program, configu-

ration, or data memory. For all system applications, they

significantly improves performance and reliability, while low-

ering power consumption. They inherently use less energy

during Erase and Program than alternative flash technolo-

gies. The total energy consumed is a function of the

applied voltage, current, and time of application. Since for

any given voltage range, the SuperFlash technology uses

less current to program and has a shorter erase time, the

total energy consumed during any Erase or Program oper-

ation is less than alternative flash technologies. These

devices also improve flexibility while lowering the cost for

program, data, and configuration storage applications.

The SuperFlash technology provides fixed Erase and Pro-

gram times, independent of the number of Erase/Program

cycles that have occurred. Therefore the system software

or hardware does not have to be modified or de-rated as is

necessary with alternative flash technologies, whose Erase

and Program times increase with accumulated Erase/Pro-

gram cycles.

To meet surface mount requirements, the SST39LF512/

010/020/040 and SST39VF512/010/020/040 devices are

offered in 32-lead PLCC and 32-lead TSOP packages. The

SST39LF/VF010 and SST39LF/VF020 are also offered in

a 48-ball TFBGA package. See Figures 1, 2, 3, and 4 for

pin assignments.

Device Operation

Commands are used to initiate the memory operation func-

tions of the device. Commands are written to the device

using standard microprocessor write sequences. A com-

mand is written by asserting WE# low while keeping CE#

low. The address bus is latched on the falling edge of WE#

or CE#, whichever occurs last. The data bus is latched on

the rising edge of WE# or CE#, whichever occurs first.

Read

The Read operation of the SST39LF512/010/020/040 and

SST39VF512/010/020/040 device is controlled by CE#

and OE#, both have to be low for the system to obtain data

from the outputs. CE# is used for device selection. When

CE# is high, the chip is deselected and only standby power

is consumed. OE# is the output control and is used to gate

data from the output pins. The data bus is in high imped-

ance state when either CE# or OE# is high. Refer to the

Read cycle timing diagram for further details (Figure 5).

Byte-Program Operation

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 are programmed on a byte-by-byte basis. Before

programming, the sector where the byte exists must be

fully erased. The Program operation is accomplished in

three steps. The first step is the three-byte load sequence

for Software Data Protection. The second step is to load

byte address and byte data. During the Byte-Program

operation, the addresses are latched on the falling edge of

either CE# or WE#, whichever occurs last. The data is

latched on the rising edge of either CE# or WE#, whichever

occurs first. The third step is the internal Program operation

which is initiated after the rising edge of the fourth WE# or

CE#, whichever occurs first. The Program operation, once

initiated, will be completed, within 20 µs. See Figures 6 and

7 for WE# and CE# controlled Program operation timing

diagrams and Figure 16 for flowcharts. During the Program

operation, the only valid reads are Data# Polling and Tog-

gle Bit. During the internal Program operation, the host is

free to perform additional tasks. Any commands written

during the internal Program operation will be ignored.

Sector-Erase Operation

The Sector-Erase operation allows the system to erase the

device on a sector-by-sector basis. The sector architecture

is based on uniform sector size of 4 KByte. The Sector-

Erase operation is initiated by executing a six-byte com-

mand sequence with Sector-Erase command (30H) and

sector address (SA) in the last bus cycle. The sector

address is latched on the falling edge of the sixth WE#

pulse, while the command (30H) is latched on the rising

edge of the sixth WE# pulse. The internal Erase operation

begins after the sixth WE# pulse. The End-of-Erase can be

determined using either Data# Polling or Toggle Bit meth-

ods. See Figure 10 for timing waveforms. Any commands

written during the Sector-Erase operation will be ignored.

Chip-Erase Operation

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 devices provide a Chip-Erase operation, which

allows the user to erase the entire memory array to the ‘1’s

state. This is useful when the entire device must be quickly

erased.

The Chip-Erase operation is initiated by executing a six-

byte Software Data Protection command sequence with

Chip-Erase command (10H) with address 5555H in the last

byte sequence. The internal Erase operation begins with

the rising edge of the sixth WE# or CE#, whichever occurs

first. During the internal Erase operation, the only valid read

is Toggle Bit or Data# Polling. See Table 4 for the command

sequence, Figure 11 for timing diagram, and Figure 19 for

the flowchart. Any commands written during the Chip-

Erase operation will be ignored.

Write Operation Status Detection

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 devices provide two software means to detect the

completion of a Write (Program or Erase) cycle, in order to

optimize the system write cycle time. The software detec-

tion includes two status bits: Data# Polling (DQ7) and Tog-

gle Bit (DQ6). The End-of-Write detection mode is enabled

after the rising edge of WE# which initiates the internal Pro-

gram or Erase operation.

The actual completion of the nonvolatile write is asynchro-

nous with the system; therefore, either a Data# Polling or

Toggle Bit read may be simultaneous with the completion

of the Write cycle. If this occurs, the system may possibly

get an erroneous result, i.e., valid data may appear to con-

flict with either DQ7 or DQ6. In order to prevent spurious

rejection, if an erroneous result occurs, the software routine

should include a loop to read the accessed location an

additional two (2) times. If both reads are valid, then the

device has completed the Write cycle, otherwise the rejec-

tion is valid.

Data# Polling (DQ7)

When the SST39LF512/010/020/040 and SST39VF512/

010/020/040 are in the internal Program operation, any

attempt to read DQ7 will produce the complement of the

true data. Once the Program operation is completed, DQ7

will produce true data. Note that even though DQ7 may

have valid data immediately following completion of an

internal Write operation, the remaining data outputs may

still be invalid: valid data on the entire data bus will appear

in subsequent successive Read cycles after an interval of 1

µs. During internal Erase operation, any attempt to read

DQ7 will produce a “0”. Once the internal Erase operation is

completed, DQ7 will produce a “1”. The Data# Polling is

valid after the rising edge of fourth WE# (or CE#) pulse for

Program operation. For Sector- or Chip-Erase, the Data#

Polling is valid after the rising edge of sixth WE# (or CE#)

pulse. See Figure 8 for Data# Polling timing diagram and

Figure 17 for a flowchart.

Toggle Bit (DQ6)

During the internal Program or Erase operation, any con-

secutive attempts to read DQ6 will produce alternating ‘0’s

and ‘1’s, i.e., toggling between 0 and 1. When the internal

Program or Erase operation is completed, the toggling will

stop. The device is then ready for the next operation. The

Toggle Bit is valid after the rising edge of fourth WE# (or

CE#) pulse for Program operation. For Sector- or Chip-

Erase, the Toggle Bit is valid after the rising edge of sixth

WE# (or CE#) pulse. See Figure 9 for Toggle Bit timing dia-

gram and Figure 17 for a flowchart.

Data Protection

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 provide both hardware and software features to

protect nonvolatile data from inadvertent writes.

Hardware Data Protection

Noise/Glitch Protection: A WE# or CE# pulse of less than 5

ns will not initiate a Write cycle.

VDD Power Up/Down Detection: The Write operation is

inhibited when VDD is less than 1.5V.

Write Inhibit Mode: Forcing OE# low, CE# high, or WE#

high will inhibit the Write operation. This prevents inadvert-

ent writes during power-up or power-down.

Software Data Protection (SDP)

The SST39LF512/010/020/040 and SST39VF512/010/

020/040 provide the JEDEC approved Software Data Pro-

tection scheme for all data alteration operation, i.e., Pro-

gram and Erase. Any Program operation requires the

inclusion of a series of three-byte sequence. The three-byte

load sequence is used to initiate the Program operation,

providing optimal protection from inadvertent Write opera-

tions, e.g., during the system power-up or power-down.

Any Erase operation requires the inclusion of six-byte load

sequence. These devices are shipped with the Software

Data Protection permanently enabled. See Table 4 for the

specific software command codes. During SDP command

sequence, invalid commands will abort the device to read

mode, within TRC.

Product Identification

The Product Identification mode identifies the devices as

the SST39LF/VF512, SST39LF/VF010, SST39LF/VF020

and SST39LF/VF040 and manufacturer as SST. This

mode may be accessed by software operations. Users

may use the Software Product Identification operation to

identify the part (i.e., using the device ID) when using multi-

ple manufacturers in the same socket. For details, see

Table 4 for software operation, Figure 12 for the Software

ID Entry and Read timing diagram, and Figure 18 for the

Software ID entry command sequence flowchart.

Product Identification Mode Exit/Reset

In order to return to the standard Read mode, the Software

Product Identification mode must be exited. Exit is accom-

plished by issuing the Software ID Exit command

sequence, which returns the device to the Read operation.

Please note that the Software ID Exit command is ignored

during an internal Program or Erase operation. See Table 4

for software command codes, Figure 13 for timing wave-

form, and Figure 18 for a flowchart.
