Overview

The STM32L071KZU6 is an ultra-low-power 32-bit microcontroller featuring an Arm Cortex-M0+ core running at 32 MHz. It is equipped with 192 KB of Flash memory, 20 KB of RAM, and 6 KB of integrated EEPROM, specifically designed to minimize power consumption in battery-operated applications.

Why Choose This Part

This MCU offers a high memory-to-pin-count ratio with 192 KB of Flash in a compact footprint, allowing for complex firmware in space-constrained designs. Its integrated 6 KB EEPROM eliminates the need for external non-volatile memory components, reducing total BOM cost and PCB area.

Applications

Battery-Powered Sensors
Optimized for remote environmental or industrial sensors where long battery life is critical due to its low-power sleep modes.
Wearable Devices
The compact package and low power profile make it suitable for fitness trackers and medical monitoring equipment.
Smart Utility Meters
Reliable performance and integrated EEPROM allow for secure data logging in electricity, gas, or water meters.
IoT End Nodes
Provides the necessary communication interfaces and memory capacity for low-power wide-area network nodes.
