Overview

The STM32L071KBT6 is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating at 32 MHz. It features 128 Kbytes of Flash memory, a hardware encryption engine, and a wide range of enhanced I/Os and peripherals designed for energy-sensitive applications.

Why Choose This Part

This MCU offers an outstanding power-to-performance ratio with multiple low-power modes, including a 0.29 microamp Standby mode. It includes a built-in EEPROM for data logging and integrated analog peripherals like a 12-bit ADC that can operate down to 1.65V.

Applications

Battery-Powered Sensors
Ideal for remote environmental monitoring where devices must operate for years on a single coin-cell battery.
Utility Metering
Used in gas and water meters that require high reliability and low power consumption during long periods of inactivity.
Wearable Devices
Suitable for fitness trackers and smartwatches needing a compact LQFP32 footprint and efficient processing.
Alarm Systems
Perfect for wireless smoke detectors and entry sensors that remain in standby mode most of the time.

Getting Started

Engineers should start with the STM32CubeL0 software package and the NUCLEO-L073RZ development board for rapid prototyping. Development is supported by industry-standard IDEs including STM32CubeIDE, Keil MDK-ARM, and IAR Embedded Workbench.
