STM32, more choice with two complete lines
The Performance line, STM32F103, operates at 72 MHz,
with more on-chip RAM and peripherals. The Access
line, STM32F101, operates at 36 MHz. Both lines are
pin-to-pin and software-compatible, and offer the same
embedded Flash options.
The Performance line takes the 32-bit MCU world
to new levels of performance and energy efficiency.

STM32 key benefits
Outstanding power efficiency
High performance does not mean high power
consumption. We have taken special care to address
three main energy requirements driven by the market:
■ High dynamic power efficiency in running mode
■ Extremely low power when the application is
in standby
■ Low-voltage capability for direct battery operation
In run mode, executing from Flash at full 72 MHz CPU
speed, the STM32 has a current consumption as low
as 27 mA.

STM32F10x: Low power
In standby mode, current consumption is as low as
2 µA typical, with reset circuitry active. Finally, its 2.0 V
to 3.6 V power supply enables its use for battery
operated applications.
The STM32 has three different low power modes and
a versatile clocking scheme so that users can optimize
power consumption versus performance.
The STM32 also embeds a real-time clock (RTC) running
either from a 32 kHz quartz oscillator or an internal
RC. The RTC has a separate power domain, with an
embedded switchover to run either from a dedicated coin
cell battery or from the main supply. Its typical current
consumption is 1.4 µA at 3.3 V. It embeds 20 bytes for
data backup. Start-up time from low-power modes is
lower than 7 µs typical from stop mode, and 55 µs typical
from standby mode and reset.

Superior and innovative peripherals
The STM32 benefits from a dual advanced peripheral
bus (APB) architecture, one of which is a high-speed
APB (up to CPU frequency). Peripherals have been
connected on this bus to increase peripheral speed:
Motor control
The STM32 Performance line embeds timers and
ADC features that are perfectly suited to three-phase
brushless motor control. The advanced control PWM
timer offers:
■ Six outputs
■ Dead-time generation
■ Edge-aligned and center-aligned waveforms
■ Emergency stop and synchronization capability
with the dual ADC, synchronization capability with
other timers
■ Programmable smoke inhibit feature to protect
registers against unwanted writing
■ Encoder input
■ Hall effect sensors interface
■ Total vector control loop: 21 µs in sensorless mode
The dual ADC architecture allows dual sample and
hold capability with 12-bit resolution, 1 µs conversion
time. The dual ADC is controlled by two independent
sequencers with discontinuous mode, multiple trigger
sources, and channel-by-channel programmable
sampling time.
This dedicated set of peripherals combined with the
high performance of the Cortex-M3 core allows your
software to shorten the total vector control loop to
21 µs (sensorless mode, three-phase PMSM motor).
The CPU load is below 25% at 10 kHz current sampling
frequency, allowing the STM32 to perform other tasks
than motor control in the application.
Supporting tools include the STM32 motor control
starter kit (STM3210B-MCKIT), a complete hardware
platform and ready-to-run demo based on the STM32
motor control firmware library. It allows rapid feature
evaluation and easy implementation of sensor and
sensorless vector-based motor control for three-phase
PMSM and AC induction motors.

STM32 easy development, fast time to market
From ideas to reality. As easy as 1, 2, 3
STM32 firmware library
The STM32 firmware library provides easy access to all features of the standard device peripherals of the STM32.
This free software package provides drivers for all standard device features and peripherals, from GPIO and timers
to CAN, I2C, EMI, SPI, UART, ADC and more.
The fully documented and tested C source code requires only basic knowledge of C programming, is compatible
with any C compiler for ARM core-based microcontrollers, and is MISRA C-compliant (latest rules).
The STM32 library shares the same API with the STR7 and STR9 libraries.
USB developer kit
The USB developer kit facilitates USB implementation in a full range of applications by providing a complete,
USB-certified firmware package that allows developers to painlessly develop any flavor of USB firmware including:
■ Control transfer with generic device management tasks
■ Interrupt transfer with HID mouse/joystick demo
■ Bulk transfer with mass storage demo
■ Isochronous transfer with voice speaker/microphone demo
The kit implements DFU for firmware updates on USB,
and Virtual COM (CDC class) for emulation of an RS232
interface on USB.
STM32 motor control firmware library for vector drive
Optimized and documented C firmware libraries for control of both PMSM and AC induction brushless motors in
vector mode (FOC) are provided for free upon request.
These modular libraries support both types of motors in standalone mode using ST hardware. The source files
are provided free of charge and are MISRA C (latest rules)-compliant, which helps for compliancy with IEC60730.
