The STM32L031K6U6TR is an ultra-low-power ARM Cortex-M0+ microcontroller from STMicroelectronics. It runs at 32MHz with 32KB flash and 8KB RAM, operating from 1.8V to 3.6V. Housed in a 32-UFQFN package, it integrates DMA, PWM, WDT, and brown-out reset, making it ideal for compact, energy-conscious IoT and portable applications.
- Ultra-low-power Cortex-M0+ core extends battery life in portable devices.
- Compact UFQFN package with exposed pad enables dense PCB layouts and better thermal performance.
- DMA controller offloads CPU, improving throughput for sensor data streaming.
- Wide voltage range (1.8V-3.6V) supports single-cell battery operation.
IoT Sensor Nodes
1.8V-3.6V operation and 32MHz Cortex-M0+ enable battery-powered environmental monitoring with low active current.
Wearable Health Monitors
UFQFN package (3x3mm) and low-power modes suit compact fitness bands tracking heart rate and motion.
Smart Home Controllers
DMA and PWM support dimming and motor control in smart blinds or thermostats, with brown-out detection for stable operation.
Portable Medical Devices
32KB flash stores calibration data; 8KB RAM handles real-time signal processing for glucose meters or pulse oximeters.
Industrial Sensor Interfaces
Exposed pad aids heat dissipation in 4-20mA loop transmitters, while DMA reduces CPU load for continuous ADC sampling.
Battery Management Systems
Low voltage threshold (1.8V) allows deep discharge monitoring in single-cell Li-ion packs.
