Overview

The STM32L562VET6 is a high-performance ultra-low-power microcontroller based on the Arm Cortex-M33 core with TrustZone for hardware-level security. Operating at up to 110MHz, it integrates 512KB of Flash and 256KB of RAM while offering an integrated SMPS step-down converter to optimize power efficiency. This device is specifically engineered for secure IoT endpoints that require advanced cryptography and long battery life.

Why Choose This Part

The inclusion of an Arm Cortex-M33 core brings TrustZone security to the ultra-low-power STM32 line, allowing for physical isolation of critical code. Developers can leverage the integrated SMPS step-down converter to significantly reduce dynamic power consumption compared to standard LDO-only regulators.

Applications

Secure IoT Endpoints
Utilizing TrustZone and the AES coprocessor to protect sensitive data and firmware integrity in connected devices.
Industrial Sensor Nodes
Low-power operation down to 62 uA/MHz in SMPS mode enables long-term deployment in remote sensing applications.
Wearable Medical Devices
Combines a small LQFP100 footprint with hardware-accelerated HASH and public key accelerators for secure health data transmission.
Mobile Payment Terminals
Features active tamper detection and on-the-fly decryption (OTFDEC) to meet high-security certification requirements.
