At 64 MHz, the Cortex-M0+ handles single-loop control, UART/SPI/I²C bridging, and sensor readout. The 16 KB Flash and 8 KB RAM limit firmware to that size; larger code requires a pin-compatible part with more Flash.
Thirty I/O lines in a 32-pin package means most pins are shared between GPIO and alternate functions.
The STM32G031K4T6 has 16 KB of Flash program memory and 8 KB of SRAM.
The supply voltage range is 1.7 V to 3.6 V on Vcc/Vdd.
Yes — the STM32G031K4T6 is part of the STM32G0 series and shares the same peripheral set, HAL drivers, and development toolchain (STM32CubeIDE, STM32CubeMX) as the rest of the family.
