STMicroelectronics has introduced the new STM32H7 MCU series that combines 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. The 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. These devices provide further security enhancement by integrating immutable root of trust, debug authentication, and hardware cryptographic accelerators that support the latest algorithms to prevent unauthorized access to code and data.
These MCUs 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. Designers also benefit from the wide range of package options, which extend from low-cost 68-pin packages to packages with up to 225 pins for applications that demand many external connections, such as large numbers of sensor inputs or communication channels.
