STMicroelectronics STM32G431 Microcontroller

32-bit MCU provides high-performance control for BLDC and other motor types

The STM32G431 32-bit microcontrollers from STMicroelectronics are based on the high-performance Arm® Cortex®-M4 32-bit RISC core, and operate at a frequency of up to 170 MHz.

 

These MCUs include two 16-bit PWM timers dedicated to motor control. The devices are suitable for the control of three-phase, low-voltage and low-current brushless dc (BLDC) or permanent magnet motors. An ST development platform marries the STM32G431 with the STSPIN830 motor driver to provide a complete solution for motor control.

 

The STM32G431 MCU processor core implements a full set of digital signal-processing instructions and a memory protection unit. The devices also embed several protection mechanisms for embedded Flash memory and SRAM, including:

  • Read-out protection
  • Write protection
  • Secure memory area
  • Proprietary code read-out protection

 

The core also features a single-precision floating-point unit which supports all the Arm single-precision data-processing instructions and all the data types.

 

The STM32G431 devices embed 128 kbytes of high-speed Flash memory, and 32 kbytes of SRAM. These MCUs also offer an extensive range of enhanced I/Os and peripherals.

 

Analogue provision includes two fast 12-bit ADCs, four comparators, three operational amplifiers, four DAC channels, an internal voltage-reference buffer and a low-power real-time clock.

 

The devices feature maximum operating-temperature ratings of up to 125°C, and run from a 1.7 V to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
