STMicroelectronics STM32H7R/S high-performance microcontrollers

STMicroelectronics has released a high-performance device that combines the performance, scalability and security of microprocessor-based systems that are typically more complex with the simplicity and integration of microcontrollers (MCUs).

Using the STM32H7 MCUs, producers of equipment like smart appliances, smart-building controllers, industrial automation and personal medical devices can evolve their products quickly as end-users’ demands continue to increase. Examples include adding richer, colourful user interfaces and performing multiple functions simultaneously, which is usually achieved with microprocessors (MPUs).

The STM32H7R and STM32H7S MCUs come with robust security features to address Internet of Things (IoT) applications, including protection against physical attacks, memory protection, code isolation to protect the application at runtime and platform authentication. The STM32H7S devices provide further security enhancement by integrating immutable root of trust, debug authentication and hardware cryptographic accelerators that support the latest algorithms to prevent unauthorised access to code and data. With these security features, the devices are targeting up to SESIP3 and PSA Level 3 certifications.

The STM32H7 MCUs combine the Cortex-M7 core, running at up to 600 MHz, with minimal on-chip memory and high-speed external interfaces. They let engineers build systems with extra performance and flexibility using simple microcontroller development tools. The devices available are further divided into the STM32H7R3/S3 general-purpose MCUs and the STM32H7R7/S7 with enhanced graphics-handling capabilities. Developers can share software extensively between the two lines, enabling efficient use of project resources and fast time to market for new products.
