Do you know the STM32H7 MCU that uses Arm security architecture to improve protection performance?

What is the STM32H7 MCU that uses the Arm security architecture to improve protection performance? What does it do? Mouser Electronics, a global authorized distributor of electronic components that focuses on introducing new products, will start stocking STMicroelectronics (ST)'s STM32H7 series microcontrollers from now on . This high-performance STM32H7 microcontroller adopts the same security concepts as the Arm® Platform Security Architecture (PSA) framework, and perfectly integrates these concepts with the enhanced security functions and services of the STM32 series to improve the protection performance of connected smart devices.

The ST STM32H7 microcontroller, available from Mouser, features a 32-bit Arm Cortex®-M7 core with a double-precision floating-point unit (FPU), up to 2MB of flash memory, and 1MB of RAM. This microcontroller integrates hardware security features such as a hardware true random number generator (TRNG) and an advanced cryptographic processor to simplify the security design of embedded applications and global Internet of Things (IoT) systems.

To enable secure loading of firmware, security keys and software services pre-installed on the microcontroller allow OEMs to deliver encrypted firmware to the foundry, eliminating the possibility of interception, copying or tampering with the code. The device writes code and verifies the function of the device, and establishes the root of trust mechanism required for the device to connect to the end-user network to complete remote online updates (OTA), so that security patches or software upgrades can be downloaded and installed during the device life cycle.

This family of microcontrollers offers additional features to further enhance performance, including Chrom-ART Accelerator™ for faster and more efficient graphical user interface processing, hardware JPEG codec for high-speed image processing, efficient direct storage Access (DMA) controller, the L1 cache that allows the microcontroller to access off-chip memory at full speed.

Multiple power domains allow developers to minimize application power consumption, while a sufficient number of I/O ports, communication interfaces, audio and analog peripherals can meet the needs of entertainment, remote monitoring and control applications. The above is an analysis of the STM32H7 MCU that uses the Arm security architecture to improve protection performance. I hope it can be helpful to everyone.
