Application note

Getting started with STM32F10xxx hardware development

Introduction

This application note is intended for system designers who require a hardware

implementation overview of the development board features such as the power supply, the

clock management, the reset control, the boot mode settings and the debug management. It

shows how to use the low-density value line, low-density, medium-density value line,

medium-density, high-density, XL-density and connectivity line STM32F10xxx product

families and describes the minimum hardware resources required to develop an

STM32F10xxx application.

Detailed reference design schematics are also contained in this document with descriptions

of the main components, interfaces and modes.
