Overview

The STM32L053C8T6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 32MHz. It features 64KB of Flash memory, 8KB of RAM, and integrates a dedicated LCD driver, making it highly suitable for battery-operated devices requiring a visual interface.

Why Choose This Part

This MCU offers exceptional power efficiency with a shutdown current as low as 0.27uA and a fast wake-up time. The inclusion of 2KB of integrated EEPROM simplifies data logging without requiring external components, and the hardware LCD driver reduces CPU overhead for display management.

Applications

Battery-Powered Instrumentation
Ideal for handheld meters and portable sensors that require long battery life and a segment LCD for data display.
Wearable Devices
The ultra-low power consumption and small 48-LQFP footprint suit fitness trackers and health monitors.
Utility Metering
Optimized for gas, water, and heat meters where the device must operate for years on a single battery while managing periodic sensor readings.
Industrial Sensing
Used in remote 4-20mA loop-powered or battery-fed industrial sensors requiring basic processing and low-power analog interfaces.
