Overview

The STM32L083RZT6 is an ultra-low-power 32-bit microcontroller featuring an Arm Cortex-M0+ core running at up to 32MHz. It integrates 192KB of Flash memory, 20KB of RAM, and a dedicated hardware AES 128-bit encryption engine for secure data handling. Designed for efficiency, it includes an integrated LCD driver and a True Random Number Generator (RNG).

Why Choose This Part

The device excels in power efficiency, consuming only 93 uA/MHz in run mode and as little as 0.29 uA in standby. It provides a high level of integration with a built-in LCD controller, hardware encryption, and 6KB of true EEPROM, reducing external component count and PCB footprint.

Applications

Battery-Operated IoT Sensors
Ideal for remote sensors requiring long battery life and secure data transmission via the integrated AES hardware accelerator.
Portable Medical Devices
Utilizes the built-in LCD driver and low-power modes to provide a user interface in power-constrained handheld diagnostic tools.
Smart Utility Meters
The 6KB of integrated EEPROM and 192KB Flash support robust data logging and firmware storage in gas or water metering applications.
Industrial Data Loggers
Features multiple communication interfaces like SPI, I2C, and USB, combined with high-density memory for local data buffering.
