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.
