64 MHz Cortex-M0+ with 64 KB Flash — entry-level workhorse
Peripherals and connectivity — what is on the die
There is no built-in USB interface. The data converter block provides 19 analog inputs multiplexed into a 12-bit ADC.
Memory sizing — 64 KB Flash, 8 KB RAM
The 64 KB Flash (64K x 8) and 8 KB SRAM (8K x 8) place this part in the value tier of the STM32G0 family. It fits firmware images for sensor fusion, basic motor control loops, and UART/SPI protocol handling.
Lifecycle — active, no end-of-life watch needed
Package and mounting — 48-LQFP, hand-solder friendly
The 7x7 mm body fits tight PCB layouts. No exposed thermal pad — junction-to-ambient thermal performance depends on copper area on the inner layers.
