TrustZone-M is a core technology developed by Arm as part of the v8-M architecture. It was designed to enforce a logical partition between Secure and Non-Secure MCU regions, acting as a building block in producing more secure MCU applications. However, on its own Trustzone-M is not MCU security.

In this session, we will examine the implementation of Trustzone-M in Renesas Cortex-M33 based RA4 and RA6 MCUs, along with the additional features that build on top of this to further enhance embedded security. Also covered will be the software development tools that provide the necessary workflows to allow customers to deliver a secure system.
