Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The STM32H523ZET6 device is a high-performance MCU based on the Arm Cortex-M33 core with 512 KB Flash, 272 KB RAM, and 250 MHz CPU.

The STM32H5 Arm® Cortex®-M33 32-bit MCU+FPU extends the STM32 high-performance portfolio and delivers enhanced performance and power efficiency. The family includes an Arm Cortex-M33 with DSP and a floating-point unit (FPU) operating at frequencies up to 250 MHz. The STM32H5 supports various security features, including a security manager. The Security Manager is a STMicroelectronics Trusted Execution Environment security framework that complies with the Arm Platform Security Architecture (PSA) specification (Armv8-M). Security Manager is designed to simplify the security development cycle for embedded applications by providing ready-to-use security services.
