Product details
Overview
STM32G431V8T6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 170 MHz (213 DMIPS), featuring 128 KB Flash with ECC, 32 KB SRAM (22 KB + 10 KB CCM), and integrated analog peripherals including dual 12-bit DACs (1 MSPS buffered), dual 16-bit ADCs (0.25 µs conversion), 4 comparators, 3 op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G431V8T6 datasheet, STM32G431V8T6 pinout, STM32G431V8T6 application, or STM32G431V8T6 equivalent, key selection criteria include FDCAN support for flexible data-rate automotive/industrial networks, UCPD interface for USB Type-C™ power delivery control, and hardware-accelerated trigonometric filtering for real-time closed-loop control.
Technical Context
The device implements a dual-bank Flash architecture with PCROP and securable memory zones, paired with an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution at 170 MHz. Its interconnect matrix routes 14 timers-including two 16-bit advanced motor-control timers with dead-time generation, emergency stop, and 8-channel PWM-to peripherals without CPU intervention.
Analog subsystem integration includes a voltage reference buffer (VREFBUF) supporting 2.048 V / 2.5 V / 2.9 V outputs, rail-to-rail comparators with programmable hysteresis, and op-amps configurable in PGA mode with external gain-setting resistors - all sharing common 1.71–3.6 V supply rails and supporting simultaneous high-speed sampling and signal conditioning.
