ST STM32U585 Series User Manual

Introduction
This document describes how to prepare STM32U585xx microcontrollers to make a secure system solution compliant with
SESIP Profile for PSA Level 3 using the STM32Cube_FW_U585_Security_certification_V1.0.0 software package included in the
STM32CubeU5 MCU Package.
The B-U585I-IOT02A board integrating the STM32U585AI microcontroller is used as the hardware vehicle to implement and test
a non‑secure application using secure services but it does not bring any additional security mechanism.
The security guidance described in this document applies to any boards based on STM32U585xx microcontrollers.
