Soren:
Hi!
We’d like to share with you an amazing demo we have on display here at Embedded World.

As the central part, we have the STM32H7S8-DK board, powered by the newly launched STM32H7R/S, a 600MHz Cortex-M7 microcontroller capable of running complex applications in one MCU.


Eric:
That’s right Soren. To showcase what this new STM32H7R/S can do, check out this IoT demo.
It features everything you would need to address the future challenges of IoT and embedded products:

A state of the art secure environment targeting SESIP Level 3 certification, secure boot, secure FW update, and secure execution with an easy and simple secure key provisioning mechanism.

It also has a great graphical user interface, powered by TouchGFX and the embedded NeoChrom GPU

There’s Cloud connectivity with secure communication using mbed-tls over ethernet but it could also be extended to wifi if needed.

And there’s lots of CPU power and resources to perform all that's required to manage a demanding application.
For this demo we opted for a home Automation use case. For instance, we’ve added some wireless and wired local connectivity. We went for Zigbee and OneWire, but it could have been other protocols like Matter or OpenThread to name just two.
We're also doing some sensor fusion and edge computing on the data coming from the connected sensors and actuators.
We're pushing this data to the cloud backend and we can also process cloud notifications and requests.
And of course, everything is executed in a secured and encrypted environment from external RAM and flash.
Soren:
That's really impressive. But how did ST achieve this? These type of applications are usually handled by MPU systems requiring external DDR, PMIC and a linux environment and all the cumbersome complexity of such environments?
Eric:
Well, using this scalable STM32H7R/S, developers are now able to run MPU-like applications on a microcontroller.
A 600Mhz STM32 MCU coupled with a large internal SRAM, a 200MHz external memory interface and security features targeting a SESIP Level 3 certification.
This allows for real-time and secure execution from external memories with best-in-class performances.
And really importantly, this STM32H7 is the cheapest of the series to-date, giving developers the freedom to choose the right type of external memory needed to run their most demanding applications.
We are really excited about this and can’t wait to see what products our customers will develop with this new/great MCU.
Soren.
Bye for now.
