STMicroelectronics’ STM32H723/733, STM32H725/735 and STM32H730 Value-Line MCUs build on the Arm Cortex-M7 core and operate at 550 MHz, said to be the fastest core speed in the market among MCUs that integrate Flash storage on-chip to run deeply embedded applications. The single-core devices are available with up to 1 MB of Flash and designed to bring high-end features such as rich graphics, AI and state-of-the-art cyber-protection to cost-sensitive products.

The devices can interact with off-chip storage while ensuring full execution performance and security. Their benchmark performance figures of 2778 CoreMark and 1177 DMIPS are realised whether working from internal or external memory, aided by features such as the Flexible Memory Controller (FMC) and Octal SPI memory interface. This lets designers tackle memory-hungry applications, such as high-resolution, full-colour graphics and video that demand a large frame buffer, to create products that deliver sophisticated and immersive user experiences.

The MCUs enable small, low-power products to deliver good functionality and performance. This makes them suitable for products that might previously have been unable to incorporate computationally intensive features such as AI, graphics and voice interaction, including home appliances, small medical devices, and industrial sensors and actuators. Several key features deliver advantages in industrial applications, including an integrated switched-mode power supply (SMPS) that overcomes dissipation constraints to allow extended-temperature operation up to 125°C. In addition, fault resilience is provided through error correction (ECC) for all memories.
