Overview

The STM32L052K8T6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 32MHz. It is designed for high efficiency in battery-operated devices, featuring 64KB of Flash memory, 8KB of RAM, and 2KB of integrated true EEPROM.

Why Choose This Part

This MCU offers a wide operating voltage range from 1.65V to 3.6V and features specialized low-power modes including a 0.27uA shutdown current. It includes a built-in True Random Number Generator (RNG) and a hardware CRC unit, which enhance security and data integrity in connected applications.

Applications

Battery-Powered Sensors
Ideal for remote environmental sensors or industrial monitors where long battery life and periodic wake-up cycles are required.
Wearable Electronics
The small 32-LQFP footprint and low power consumption suit compact consumer devices like fitness trackers and smart watches.
USB Low-Power Peripherals
Utilizes the integrated USB 2.0 crystal-less interface for energy-efficient PC peripherals and data loggers.
