Product details

The STM32G051K8U6 is a 32-bit MCU from ST's STM32G0 series, built around an ARM Cortex-M0+ core clocked at 64 MHz. It carries 64 KB of Flash and 18 KB of RAM, which together handle moderate firmware footprints — think sensor fusion, motor-control loops, or communication protocol stacks — without needing external memory.

The data converters are a 12-bit SAR ADC and two 12-bit DACs, suitable for analog signal conditioning without an external converter.

Housed in a 32-UFQFN exposed pad package (5x5 mm body), this MCU fits tight PCB layouts. The pad also provides a low-impedance ground return, which helps with EMI in switching applications.

Frequently asked questions

What is the difference between STM32G051K8U6 and STM32G071K8?

The STM32G071K8 is a higher-tier member of the STM32G0 family with more Flash (128 KB vs 64 KB), more RAM (36 KB vs 18 KB), and additional peripherals such as a CAN-FD interface and a 12-bit DAC with higher resolution. Both share the same ARM Cortex-M0+ core and 32-UFQFPN package footprint, but the G071 targets applications needing more memory and CAN connectivity. Pin compatibility across the series is not guaranteed — check the specific package variant.

Can STM32G051K8U6 be programmed with ST-Link?

Yes, ST-Link programmers (standalone or integrated on ST's Nucleo/Discovery boards) support the STM32G0 series via the SWD interface. The BOOT0 pin strapping and SWD pins are standard across the family — no special adapter needed.
