20-TSSOP package and board-fit constraints
The STM32G030F6P6TR: Surface-mount only; the 17 available I/O share the package perimeter with supply and ground pins, so every signal pin must earn its place in the BOM before the layout locks.
64 MHz Cortex-M0+ and memory budget
The ARM Cortex-M0+ core runs at 64 MHz — the flash wait-state profile at this speed determines the actual instruction throughput; expect one wait state above 24 MHz on the 32 KB embedded Flash. 8 KB SRAM leaves roughly 2–3 KB for the application stack and heap after the HAL and RTOS kernel footprint — a bare-metal or lightweight scheduler fits; a full FreeRTOS build with multiple queues will pressure the RAM ceiling.
Serial connectivity and peripheral mix
The 16-channel 12-bit ADC samples at up to 2 MSps in the G0 series; the conversion result is DMA-able, which keeps the CPU free for control loops during multi-channel scans. PWM timers support complementary outputs and dead-time insertion — suitable for half-bridge motor drives or LED dimming at up to the timer clock frequency divided by the prescaler.
The base product number STM32G030 covers multiple memory and package variants; the F6 suffix denotes 32 KB Flash / 20-TSSOP, and the P6TR suffix indicates tape-and-reel packaging. Cut-tape quantities are also available for prototype builds.
