STMicroelectronics STM32H5 microcontroller

Click2Contact

The STM32H5 is the new reference mainstream microcontroller featuring powerful Cortex-M33 implementation that is designed to reach 1017 points in CoreMark because of its extensive security capabilities. The device runs at 250 MHz. It houses up to 2 MB of dual bank Flash and up to 640 KB of RAM. It also draws from previous models to offer a CORDIC and FMAC accelerator, as in the STM32G4.

Similarly, it takes the security features of the STM32U5 and builds on them by inaugurating the ST immutable Root of Trust (iRoT) and updatable Root of Trust (uRoT), among other things. The device will have a SESIP Level 3 certification. The device also adds more features, such as a two-stage root of trust: the immutable and updatable root of trust or iRoT and uRoT. As the name implies, the former is set at the factory and cannot be modified. It uses a read-only memory containing keys and other mechanisms defined by ST to establish a secure boot without external keys.
