Overview

The STM32L071VZT6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core operating at 32MHz. It provides a generous 192KB of Flash memory and 6KB of integrated data EEPROM, making it suitable for high-density code and non-volatile data storage in power-sensitive applications.

Why Choose This Part

This MCU offers a high memory-to-power ratio with 192KB of Flash and 20KB of RAM while maintaining very low current consumption. The inclusion of hardware oversampling and ultra-low-power comparators allows for efficient analog signal processing at reduced clock speeds.

Applications

Battery-Powered Data Loggers
The 6KB of integrated EEPROM allows for efficient storage of configuration and sensor calibration data without consuming Flash cycles.
Remote Industrial Sensors
Uses multiple low-power modes, including a 0.29uA shutdown current, to maximize battery life in field-deployed instrumentation.
Utility Metering
The high pin count (100-LQFP) and 84 I/Os provide extensive connectivity for complex meter interfaces and communication modules.
