Overview

The STM32L052C8T6 is an ultra-low-power 32-bit microcontroller featuring an ARM Cortex-M0+ core running at up to 32MHz. It is specifically designed for energy-efficient applications, integrating 64KB of Flash memory, 8KB of RAM, and 2KB of true data EEPROM within a 48-pin LQFP package.

Why Choose This Part

This MCU offers a high performance-to-power ratio with a Cortex-M0+ core and advanced power management features like a 1.65V to 3.6V operating range. It includes unique features for its class such as 2KB of integrated EEPROM and hardware oversampling for high-resolution analog measurements.

Applications

Battery-Powered Sensors
Ideal for remote IoT nodes requiring long battery life due to the 0.6uA standby mode and low-power run modes.
USB Peripherals
Utilizes the integrated crystal-less USB 2.0 interface for cost-effective PC accessories and data loggers.
Portable Medical Devices
Supports handheld diagnostic tools using its integrated capacitive sensing and 12-bit ADC for sensor interfacing.
