Overview

The STM32L052K6T6 is an ultra-low-power 32-bit microcontroller featuring an ARM Cortex-M0+ core running at 32MHz with 32KB of Flash and 2KB of dedicated data EEPROM. Part of ST's L0 series, it is specifically designed for high efficiency in battery-operated devices, featuring a crystal-less USB 2.0 interface and a comprehensive set of power-saving modes.

Why Choose This Part

This MCU offers a unique combination of high performance and low power, drawing only 2.6mA at 16MHz in run mode. The integration of 2048 bytes of true EEPROM simplifies data logging and configuration storage without the wear-leveling complexity of Flash-based emulation.

Applications

Battery-Powered USB Peripherals
Utilizes the crystal-less USB 2.0 interface to reduce BOM cost and power consumption in portable computer accessories.
Remote Sensors
Leverages the 0.27uA shutdown current and 0.29uA standby current for long-term deployments in environmental monitoring.
Portable Healthcare Monitors
Integrates an 8KB RAM and hardware oversampling to handle biometric data processing in small, wearable form factors.
Capacitive Touch Interfaces
Built-in capacitive sensing channels support the implementation of touch keys and sliders without external controllers.
