The peripheral list also includes brown-out detect, POR, PWM timers, a watchdog, and DMA, so the part can handle motor-control or power-conversion feedback loops with minimal CPU intervention. ## Active lifecycle — no sourcing headache The base product number STM32G431 covers a range of Flash and RAM density variants in the same 64-LQFP footprint, so a future density upgrade stays pin-compatible without a board spin.","metaTitle":"STM32G431R6T6 ARM Cortex-M4 MCU, 170 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32G431R6T6 32-bit ARM Cortex-M4 MCU at 170 MHz with 32 KB Flash, 32K x 8 RAM, 52 I/O.
