The new STM32H7 MCUs are able to deliver the power efficiency required for machine-learning applications and the performance for future neural networks.
To assist with security, the family of devices features state-of-the-art cyber-protection, including secure boot / Root-of-Trust and hardware cryptographic/hash accelerators. On-the-fly decryption (OTFDEC) extends protection to code stored in external serial memories by allowing encrypted content to be decrypted in real-time. The MCUs have embedded secure-loading services that allow users to order standard products anywhere in the world and deliver encrypted firmware to the programming partner without exposing secrets at any stage. When the product is authenticated and securely programmed, the Root-of-Trust mechanism supports all secure firmware services including field update.
The new devices offer rich digital-communication interfaces and up to two octal SPI external memory interfaces. They also have an RGB interface for up to XGA displays, ST’s Chrom-ART Accelerator that offloads the CPU from 2D graphics operations, Chrom-GRC that optimizes support for non-rectangular displays, and hardware JPEG codecs.
