A member of the STM32H7 series supporting the PSA, the STM32H753 MCU with Arm’s highest-performing embedded core (Cortex-M7) delivers peak performance of 2020 CoreMark/856 DMIPS running at 400 MHz, executing code from embedded Flash memory. Features include the Chrom-ART Accelerator for fast and efficient graphical user-interfaces, a hardware JPEG codec that allows high-speed image manipulation, efficient Direct Memory Access (DMA) controllers, up to 2 MB 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 analogue peripherals can address a wide range of entertainment, remote-monitoring, and control applications.
“Security is a major priority to ensure the success of the IoT. Winning the confidence of end users – from individual consumers to businesses and government agencies – is critical to adoption,” said Michel Buffa, Microcontroller Division General Manager, STMicroelectronics. “PSA from Arm is making core security capabilities like device identity and over-the-air (OTA) updates more affordable and scalable for small autonomous IoT devices, and we’ve made it work with the existing security features of STM32 microcontrollers, including on our high-performing STM32H7 series.”
ST’s STM32H7 MCU devices integrate hardware-based security features including a True Random-Number Generator (TRNG) and advanced cryptographic processor, which will simplify protecting embedded applications and global IoT systems against attacks such as eavesdropping, spoofing, or man-in-the-middle interception. 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.
ARM adds, “The secure hardware blocks and firmware-loading services ST has embedded in the Cortex-M based STM32H7 series utilizes the Arm PSA principles to drive innovation in security for a broad range of applications, including communication gateways and connected objects.”
The STM32H753 is priced at $8.90 (10,000).
