Overview

The STM32L071KZT6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 32MHz. It integrates 192KB of Flash memory and 20KB of RAM, specifically optimized for battery-operated devices requiring long service life and high efficiency.

Why Choose This Part

This MCU offers an exceptional balance of memory and power efficiency, featuring a shutdown current as low as 0.29uA. It includes hardware features such as an MPU, CRC calculation unit, and multiple serial interfaces including LPUART for low-power communication.

Applications

Battery-Powered Sensors
Ideal for remote environmental sensors or smart meters where low power consumption in Stop and Standby modes is critical.
Industrial Monitoring
Utilizes integrated DMA, ECC, and wide voltage range (1.65V to 3.6V) for reliable operation in industrial signaling applications.
Portable Consumer Electronics
The small 32-LQFP footprint and built-in 6KB EEPROM make it suitable for storing user configuration and logging data in hand-held devices.
