Trends in the industrial automation and IIoT market segments show an increase in human interaction with smart devices, and a growing need for enhanced security. Remote healthcare monitoring, self-care, real-time solutions and digitalized smart medical devices require low-cost and efficient microcontrollers to drive smaller displays capable of presenting visually rich graphics and important quantitative data.

To meet these market challenges, a new addition to the STM32 family has been developed. Introducing the STM32H7A3/B3 line of Arm® Cortex®-M7 microcontrollers, featuring a unique blend of peripherals targeting embedded designs in the high-quality graphics, AI, and voice UI application segments.

During this session, we will present the STM32H7A3/B3 architecture and security infrastructure including Secure Boot Secure Firmware Update (SBSFU) and Secure Firmware Install (SFI) applications, as well as a number of application use cases. 

You will learn:

  • How to use our comprehensive development ecosystem to create a smartphone-like graphic UI for your embedded device with minimum cost and effort.
  • How the power efficiency of the STM32H7A3/B3 improves autonomy down to 32 µA in STOP mode with full RAM retention.
  • About embedded security features to protect your application and secure firmware update.
