Overview

The STM32H523CET6 is a high-performance 32-bit microcontroller based on the Arm Cortex-M33 core operating at up to 250 MHz. It features 512KB of Flash memory and 272KB of SRAM, integrating advanced security through Arm TrustZone and an MPU for robust IoT applications. This MCU balances high computational throughput with integrated hardware acceleration for efficient data processing.

Why Choose This Part

The STM32H523CET6 offers a significant performance boost over standard M4-based MCUs while adding essential hardware-level security features like TrustZone. It includes ECC on both Flash and SRAM for high-reliability requirements and a flexible external memory controller for system expansion. The 250 MHz operating frequency provides ample headroom for concurrent communication and control tasks.

Applications

Secure IoT Gateways
Utilizes Arm TrustZone and v8-M security extensions to isolate critical security firmware from application code.
Industrial Control Systems
