Product details

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.

Frequently asked questions

Is STM32G071KBT3 a good alternative to STM32G071KBT6?

Yes — both share the same STM32G071 core, 64 MHz Cortex-M0+, 128 KB Flash, and 36 KB RAM. The difference is the package: the KBT3 comes in a 32-LQFP, while the KBT6 is a 48-LQFP with more I/O. If your board layout and pin count fit 32 pins, the KBT3 is a drop-in functional alternative at a lower pin-count package.
