The 11-channel 12-bit ADC and four 12-bit DACs let it sample phase currents and output analog setpoints without external converters — a common BOM simplification on servo-drive and battery-charger boards.
Package and thermal: 32-UFQFPN with exposed pad
Housed in a 32-UFQFN exposed-pad package (5x5 mm body), this MCU is a surface-mount part that needs the central thermal pad soldered to a PCB copper island for both mechanical stability and heat sinking. The 26 I/O are brought out on the perimeter; the pad itself is not a signal pin but must be connected to ground (or the appropriate supply plane per the datasheet layout guidelines).
Supply range and power-on reset
The integrated brown-out detect and POR (power-on reset) peripherals mean no external supervisor IC is needed for basic reset sequencing — a cost and board-area saving on high-density designs.
STMicroelectronics lists the STM32G431KBU3 as an active product — no NRND or EOL flags, no last-time-buy window.
