Overview

The STM32L071KBU6 is an ultra-low-power microcontroller based on the Arm Cortex-M0+ core, operating at 32 MHz. It features 128 KB of Flash memory and is specifically designed for high-efficiency applications where battery life is a critical design constraint.

Why Choose This Part

This MCU offers a highly efficient power-to-performance ratio with specialized low-power modes and a fast wake-up time. Its internal voltage scaling and ultra-low-leakage peripherals make it an excellent choice for energy-sensitive designs.

Applications

Battery-Powered IoT Sensors
Ideal for remote monitoring nodes requiring long service life from a single coin cell or LiPo battery.
Portable Medical Devices
Suitable for hand-held diagnostic tools and wearable health trackers that benefit from low-power consumption and a small footprint.
Utility Metering
Commonly used in smart gas and water meters where minimal power draw is required for decade-long operation.

Getting Started

Develop using the STM32Cube ecosystem, including STM32CubeIDE and the STM32CubeL0 firmware package. For hardware evaluation, the NUCLEO-L073RZ provides a compatible development path for the L0 series, while the ST-LINK/V2 or V3 is required for debugging.
