That density of analog front-end means a single STM32G431KBU6 can sense multiple current/voltage feedback points and generate analog setpoints or reference levels without external converter ICs, shrinking the mixed-signal BOM for a servo drive or a programmable power supply. CANbus support is a single channel, enough for industrial fieldbus or automotive sub-net communication. The peripheral list also includes DMA, PWM timers, brown-out detect, and a watchdog — a complete set for a standalone controller node. ## Package and supply range The STM32G431KBU6 is a surface-mount part in a 32-UFQFN Exposed Pad package (5x5 mm body) with 26 I/O.","metaTitle":"STM32G431KBU6 STM32G4 MCU, 170 MHz ARM Cortex-M4F","metaDescription":"STM32G431KBU6 32-bit MCU with 170 MHz ARM Cortex-M4F, 128 KB Flash, 32 KB SRAM, 11x12b ADC, 4x12b DAC, CANbus.
