Overview

The STM32L562QEI6 is an ultra-low-power microcontroller based on the ARM Cortex-M33 core with TrustZone technology. Operating at up to 110MHz, it integrates hardware acceleration for AES and public key cryptography alongside an SMPS step-down converter to achieve industry-leading power efficiency of 62 microamps per MHz.

Why Choose This Part

It offers a unique balance of high performance and advanced security features, including OTFDEC for real-time decryption of external Octo-SPI memories. The inclusion of an integrated SMPS and FlexPowerControl allows engineers to optimize power consumption across nine different low-power modes while maintaining 256KB of SRAM.

Applications

Secure IoT Nodes
Leveraging TrustZone and the hardware cryptographic accelerators (AES, PKA, HASH) to protect sensitive data and provide root-of-trust functionality in connected devices.
Wearable Technology
Utilizing the 132-UFBGA package and ultra-low-power modes like Shutdown (17nA) to extend battery life in compact, sophisticated wearable applications.
Secure Industrial Sensors
Implementing Batch Acquisition Mode (BAM) to collect sensor data via I2C, SPI, or UART while the core remains in a low-power state.
