Product details

The STM32G031K6U6 is a 32-bit ARM Cortex-M0+ microcontroller from ST's STM32G0 series, clocked at 64 MHz. The 18-channel 12-bit SAR ADC covers a dense sensor array — think eight analog inputs for a temperature multiplexer plus a few for voltage and current monitoring — without needing an external MUX.

The 64 MHz Cortex-M0+ handles a control loop with margin for background communications and ADC reads. If the firmware fits in 32 KB, this part is the right BOM fit.

We source and quote this part to order against an RFQ.
