Product details

64 MHz Cortex-M0+ in a 20-pin TSSOP — what fits in this footprint

The 8 KB RAM handles a couple of DMA buffers for the 12-bit ADC (17 channels) without spilling into stack overflow. If your application needs over-the-air firmware updates or a larger lookup table, step up to the 64 KB Flash variants in the same package.

For a 3.3 V regulated rail, the 1.7 V floor gives margin during cold-crank dips.

This makes it a safe choice for a new BOM line or a production ramp — no forced redesign horizon from the supplier side.

Frequently asked questions

What is the difference between STM32G041F6P6 and STM32G031F6P6?

The G041 adds a 12-bit ADC with 17 channels (vs 16 on the G031) and includes I²S and IrDA connectivity not present on the G031. The G041 also integrates a brown-out detect and POR block that the G031 lacks. Pin-compatible in the same package, so a swap requires only a firmware change.

Does STM32G041F6P6 have 5V tolerant I/O?

No. Driving a 5 V logic input without a level shifter risks exceeding the absolute maximum ratings. Use an external translator or a 3.3 V-tolerant peripheral.
