Overview

The STM32L562ZET6 is an ultra-low-power 32-bit microcontroller based on the Arm Cortex-M33 core with TrustZone hardware security. Operating at up to 110MHz, it integrates 512KB of Flash memory and 256KB of SRAM with advanced cryptographic accelerators and active tamper detection. This device is specifically engineered for secure IoT endpoints that require a balance between high performance and strict power efficiency.

Why Choose This Part

The inclusion of Arm TrustZone provides hardware-level isolation for sensitive code and peripherals, significantly simplifying security certification. It features a highly efficient power profile, consuming as little as 17nA in shutdown mode and 11.04mA during high-performance 110MHz operation. Integrated accelerators for AES, HASH, and public key operations offload the CPU for faster cryptographic processing.

Applications

Secure IoT Gateways
Utilizes TrustZone and the AES/Public Key accelerators to manage secure cloud connectivity and encrypted data routing.
Industrial Sensor Nodes
Leverages the 110MHz clock speed and 14-bit ADC for high-precision data acquisition while maintaining ultra-low power consumption in standby modes.
Smart Metering
The integrated active tamper detection and on-the-fly decryption engine protect sensitive metering data from physical and side-channel attacks.
