Application note

Getting started with STM32U5 MCU hardware development

Rev 7 - November 2023

Introduction

This application note is intended for system designers who require a hardware implementation overview of the development board features: power supply, clock management, reset control, boot mode settings, and debug management.

It details how to use the STM32U5 series microcontrollers (named STM32U5) and describes the minimum hardware resources required to develop an application using these MCUs.

This document also includes detailed reference design schematics with the description of the main components, interfaces, and modes.

General information

This document applies to the STM32U5 series Arm® Cortex®‑M33‑based microcontrollers.
