ST’s STM32H7 MCUs are based on a 32-bit Arm Cortex-M7 core with double-precision FPU, up to 2 Mbyte Flash and 1 Mbyte RAM. The MCUs integrate hardware-based security features including a True Random-Number Generator (TRNG) and advanced cryptographic processor.
Security keys and software services on the MCU allow OEMs to provide manufacturing partners with already encrypted firmware. This enables programming and authenticating the device to establish the root-of-trust mechanism needed for the device to be connected to the end-user’s network and remotely updated over the air for security patches or feature upgrades.
The Chrom-ART Accelerator provides fast GUIs, a hardware JPEG codec allows high-speed image manipulation, highly efficient Direct Memory Access controllers, and the L1 cache allows full-speed interaction with off-chip memory. Multiple power domains allow engineers to minimise the energy consumed by their applications, while plentiful I/Os, communication interfaces, and audio and analogue peripherals are available.
