The STMicroelectronics STM32L031K6U3 is an ultra-low-power 32-bit MCU based on the ARM Cortex-M0+ core, running at 32MHz. It provides 32KB of flash and 8KB of RAM in a compact 32-UFQFN package. With a supply voltage range of 1.65V to 3.6V and an extended temperature range of -40°C to 125°C, this device is designed for energy-efficient and rugged applications. Integrated features include brown-out detection, DMA, POR, PWM, and WDT.
- Ultra-Low Power: The Cortex-M0+ core and 1.65V operation enable battery-powered designs with minimal energy consumption.
- Extended Temperature Range: Rated for 125°C, it can be used in high-temperature environments like engine bays or industrial ovens.
- Compact Footprint: The 32-UFQFN package with exposed pad offers excellent thermal performance in a small area.
- Comprehensive Protection: Brown-out detect, POR, and WDT provide robust system supervision for unattended operation.
Battery-Powered IoT Sensor
The ultra-low 1.65V minimum supply and low-power modes of the Cortex-M0+ core enable years of operation from a single coin cell in wireless environmental sensors.
Wearable Health Monitor
Its compact 32-UFQFN package and 125°C rating make it suitable for skin-contact devices that measure heart rate or temperature, with the DMA handling sensor data efficiently.
Industrial Probe
The wide temperature range and brown-out detection ensure reliable operation in industrial probes used for measuring pressure or flow in extreme conditions.
Smart Home Controller
With 32KB flash and PWM outputs, it can control LED lighting, small fans, or smart locks, while the POR and WDT maintain system integrity.
Portable Instrument
The 1.65V operation allows direct battery connection without a regulator, simplifying design of handheld multimeters or calibration tools.
Automotive Aftermarket
Although not AEC-Q100, its 125°C rating and robust features make it viable for non-safety automotive modules like interior lighting controllers.
