The STMicroelectronics STM32L071CBU6 is a 32MHz ARM Cortex-M0+ MCU with 128KB flash and 20KB RAM. It operates from 1.65V to 3.6V in a 48-UFQFN package. Features include brown-out detection, DMA, I2S, PWM, temp sensor, and WDT for ultra-low-power applications.
- Ultra-low-power Cortex-M0+: Extends battery life in energy-harvesting and portable designs.
- 1.65V minimum supply: Operates from a single alkaline cell or Li-ion at low charge.
- Integrated temp sensor: Saves external thermistor cost and PCB space.
- 128KB flash / 20KB RAM: Balanced memory for complex IoT applications.
Battery-Powered IoT Sensors
The 1.65V minimum supply and low-power modes extend coin-cell life in wireless temperature/humidity monitors.
Smart Agriculture Probes
Internal temp sensor and 128KB flash support soil moisture calibration curves with long deployment intervals.
Portable Medical Thermometers
High accuracy ADC and temp sensor enable clinical-grade temperature measurement with minimal external components.
Industrial 4-20mA Loop Transmitters
