MCU series leverages ARM’s Platform Security Architecture
In addition, secure firmware loading facilities help OEMs ensure their products can be programmed safely and securely, even off-site at a contract manufacturer or programming house. To enable secure loading, security keys and software services already on-board the MCU permit OEMs to provide manufacturing partners with already-encrypted firmware, making intercepting, copying, or tampering with the code impossible. 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 (OTA) to apply security patches or feature upgrades throughout the lifetime of the device.
A member of the STM32H7 series supporting the PSA, the STM32H753 MCU with ARM’s highest-performing embedded core (Cortex-M7) delivers a record performance of 2020 CoreMark/856 DMIPS running at 400MHz, executing code from embedded Flash memory. Additional features include the Chrom-ART Accelerator for fast and efficient graphical user-interfaces, a hardware JPEG codec that allows high-speed image manipulation, highly efficient Direct Memory Access (DMA) controllers, up to 2MB of on-chip dual-bank Flash memory with read-while-write capability, and the L1 cache allowing full-speed interaction with off-chip memory. Multiple power domains allow developers to minimize the energy consumed by their applications, while plentiful I/Os, communication interfaces, and audio and analog peripherals can address a wide range of entertainment, remote-monitoring, and control applications.
