Description

The STM32G431x6/x8/xB devices are based on the high-performance Arm® Cortex®-M4

32-bit RISC core. They operate at a frequency of up to 170 MHz.

The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all

the Arm single-precision data-processing instructions and all the data types. It also

implements a full set of DSP (digital signal processing) instructions and a memory protection

unit (MPU) which enhances the application’s security.

These devices embed high-speed memories (up to 128 Kbytes of Flash memory, and

32 Kbytes of SRAM), an extensive range of enhanced I/Os and peripherals connected to

two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

The devices also embed several protection mechanisms for embedded Flash memory and

SRAM: readout protection, write protection, securable memory area and proprietary code

readout protection.

The devices embed peripherals allowing mathematical/arithmetic function acceleration

(CORDIC for trigonometric functions and FMAC unit for filter functions).

They offer two fast 12-bit ADCs (4 Msps), four comparators, three operational amplifiers,

four DAC channels (2 external and 2 internal), an internal voltage reference buffer, a low-

power RTC, one general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor

control, seven general-purpose 16-bit timers, and one 16-bit low-power timer.

They also feature standard and advanced communication interfaces such as:

- Three I2Cs

- Three SPIs multiplexed with two half duplex I2Ss

- Three USARTs, one UART and one low-power UART.

- One FDCAN

- One SAI

- USB device

- UCPD

The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C

junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of

power-saving modes allows the design of low-power applications.

Some independent power supplies are supported including an analog independent supply

input for ADC, DAC, OPAMPs and comparators. A VBAT input allows backup of the RTC and

the registers.

The STM32G431x6/x8/xB family offers 9 packages from 32-pin to 100-pin.
