Application note
Getting started with STM32H74xI/G and STM32H75xI/G
hardware development
Introduction
This application note is intended for system designers who develop applications based on
STM32H750 Value line, STM32H742, STM32H743/753, STM32H745/755 and
STM32H747/757 lines, and who need an implementation overview of the following
hardware features:
• Power supply
• Package selection
• Clock management
• Reset control
• Boot mode settings
• Debug management.
This document describes the minimum hardware resources required to develop an
applica
tion based on STM32H74xI/G and STM32H75xI/G microcontrollers.
