Product details

32 MHz core — timing margin for low-power loops

The STM32L011G3U7: The 32 MHz Cortex-M0+ core delivers enough throughput for sensor polling, control loops, and communication protocol handling without exceeding the power budget of a coin cell or two AA batteries. The 8 KB Flash and 2 KB RAM limit firmware to compact, single-purpose applications — think I²C temperature sensor readout, SPI flash logging, or simple PWM dimming — not complex RTOS stacks.

For BOM planning, treat this part as approaching NRND.

Frequently asked questions

What is STM32L011G3U7's listed speed?

The STM32L011G3U7 runs at 32 MHz, which is the maximum core clock for this ultra-low-power Cortex-M0+ device.

What is the closest pin-compatible alternative to STM32L011G3U7?

The STM32L031G6U7 or STM32L051G8U7 are pin-compatible upgrades within the same 28-UFQFPN footprint, offering more Flash and RAM while maintaining the same peripheral set and supply range.
