ST’ high-performance microcontrollers pave the way to new innovations in smart home and industrial systems

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

Using these new STM32H7 MCUs, producers of equipment like smart appliances, smart-building controllers, industrial automation, and personal medical devices can evolve their products more quickly and cost effectively 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 (MPU).

ST’s new STM32H7R and STM32H7S microcontrollers come with robust security features, needed to address Internet of Things (IoT) applications. They include 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, meeting the highest industry standards for cyber protection.

The STM32H7 MCUs combine the highest-performing Arm Cortex-M core ST has yet announced (Cortex-M7 running at up to 600MHz) with minimal on-chip memory and high-speed external interfaces. They let engineers build systems with extra performance and flexibility using simple, low-cost 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 faster time to market for new products.

ST’s new STM32H7 MCUs are scheduled to enter volume production from April 2024. Sample requests and pricing information are available from local ST sales offices.

The STM32H7S8-DK demonstration and development platform, and the affordable and extendable NUCLEO-H7S3L8 MCU board, are available to accelerate building applications using the new devices.
