Application note
Getting started with STM32F4xxxx MCU hardware development
Introduction
This application note is intended for system designers who require an overview of the
hardware implementation of the development board, with focus on features like
• power supply
• package selection
• clock management
• reset control
• boot mode settings
• debug management.
This document shows how to use the high-density high-performance microcontrollers listed
in
Table 1, and describes the minimum hardware resources required to develop an
application based on those products.
Detailed reference design schematics are also contained in this document, together with
descriptions of the main components, interfaces and modes.
