Product details

64 MHz Cortex-M0+ in a 32-LQFP — what the memory and speed mean for your BOM

For a motor-control loop or a sensor hub polling at 10 kHz, the Cortex-M0+ pipeline keeps interrupt latency predictable. The 8 KB SRAM is the hard limit for stack, heap, and DMA buffers; if your application needs a large frame buffer or multiple protocol stacks, step up to the 18 KB or 36 KB RAM variants in the G0 family.

Industrial temperature grade and peripheral fit

The brown-out detect and POR simplify power sequencing on a shared rail.

Frequently asked questions

Is STM32G031K8T6U a direct replacement for STM32G031K6?

The STM32G031K6 is the lower-density sibling in the same G0 family — it has 32 KB Flash instead of 64 KB. Both share the same 32-LQFP package and pinout, so the STM32G031K8T6U is a drop-in hardware replacement with double the program memory. Firmware that fits in 32 KB will run unmodified; if the original code used the full 32 KB, the extra headroom is a bonus.
