The 12-bit ADC samples 18 external channels, covering multi-sensor analog front ends. Serial connectivity covers I2C, SPI, and UART/USART with LIN and IrDA support, so it can talk to common sensor modules, display drivers, and CAN transceivers via a UART bridge.
The MCU provides 30 general-purpose I/O pins, which includes the digital I/O lines available on the 32-pin package.
Within the STM32G0 series, the STM32G031K8U6 shares the same 32-UFQFPN footprint and pinout, but runs at a lower 64 MHz core with reduced memory options. For a direct drop-in with identical memory and speed, the STM32G041K8U6 is the baseline; higher-density siblings like the STM32G041KBU6 (128 KB Flash) use the same package but require firmware changes for the larger memory map.
