64 MHz Cortex-M0+ — enough headroom for most control loops
Peripheral set — what the 30 I/O pins actually connect to
With 30 I/O in a 32-LQFP package, this MCU packs a lot of peripheral options into a small footprint. Brown-out detect, POR, DMA, and a PWM timer set are built in, reducing external supervisor and glue logic.
That makes it a safe choice for a new design or a production ramp — no last-time-buy math required. For dual-sourcing flexibility, the STM32G0 family includes pin-compatible density variants; the base product number is STM32G071, so any G071 device in the same package footprint shares the same pinout and peripheral map.
