Overview

The STM32L552VET6 is a high-performance, ultra-low-power microcontroller based on the ARM Cortex-M33 core with TrustZone for hardware-level security. Operating at 110MHz, it features an integrated SMPS step-down converter to optimize power consumption, delivering 62 uA/MHz in buck mode. This 100-LQFP device includes 512KB of Flash with ECC and 256KB of RAM, making it suitable for secure IoT edge applications.

Why Choose This Part

This MCU provides a unique balance of security and efficiency by combining TrustZone architecture with ST's FlexPowerControl and ART Accelerator. It supports a wide operating voltage from 1.71V to 3.6V and features 83 I/O pins, offering significant flexibility for complex peripheral integration in a compact 14x14mm package.

Applications

Secure IoT End-Nodes
Utilizes Arm TrustZone and hardware cryptographic accelerators to isolate sensitive code and data in connected devices.
Industrial Sensor Hubs
Leverages 16x12-bit ADC channels and high-speed connectivity like CANbus and QSPI for real-time data acquisition and processing.
Battery-Powered Wearables
Optimizes energy efficiency using multiple low-power modes, such as the 127 uA shutdown mode and efficient SMPS regulation.
