The STM32H7 series now includes dual-core microcontrollers with Arm® Cortex®-M7 and Cortex®-M4 cores able to run up to 480 MHz and 240 MHz respectively. Our single-core Cortex®-M7 STM32H7 series also benefits from this frequency increase and can now run up to 480 MHz as well. Dual-core STM32H7 microcontrollers are available with an embedded SMPS for improved dynamic power efficiency.

    Extended temperature range support up to 125 °C (*) (ambient) will be available for certain devices for use in harsh environments including industrial applications.

    STM32H7 devices embedding a crypto/hash processor support security services such as Secure Firmware Install and Secure Boot – Secure Firmware Upgrade allowing the installation of new application code in a secured manner.

    All the other features that have made single-core STM32H7 MCUs a success are still available in the dual-core versions. The STM32H7 series remains more than ever the microcontroller with an embedded Flash memory offering the highest performance on the market.

Dual-core STM32H7 series of high-performance MCUs with Arm® Cortex®-M7 and M4 cores

    Taking advantage of an L1 cache, STM32H7 devices deliver the maximum theoretical performance of the Cortex-M7 and Cortex-M4 cores, regardless if code is executed from embedded Flash or external memory: 3224 CoreMark /1327 DMIPS at 480 MHz fCPU.

Smart architecture with new-generation peripherals

    The STM32H7 series unleashes the Cortex-M7 core:
