Analog integration — 11 ADC channels and 4 DAC outputs
On-chip data converters include eleven 12-bit ADC channels and four 12-bit DAC outputs. 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.
