With 32 KB of program flash and 8 KB of SRAM, the firmware and data budget is tight: a full HAL plus a lightweight RTOS leaves roughly 4–6 KB for the application heap and stack. ## I/O and peripheral count With 26 I/O in a 28-pin package, nearly every pin is functional — there is little headroom for expansion beyond the listed connectivity (I²C, SPI, USART, IrDA, LIN, SmartCard). The 17-channel 12-bit SAR ADC covers analog inputs, but the lack of a DAC limits closed-loop analog output applications without external components.","metaTitle":"STM32G031G6U6 STM32G0 MCU, 64 MHz, 32 KB Flash, 28-UFQFPN","metaDescription":"STM32G031G6U6 ARM Cortex-M0+ MCU, 64 MHz, 32 KB Flash, 8 KB RAM, 26 I/O, -40 to 85°C, 28-UFQFPN.
