Application note

I2C timing configuration tool

for STM32F3xxxx and STM32F0xxxx microcontrollers

Introduction

This application note presents the I2C timing configuration tool for the STM32F3xxxx and

STM32F0xxxx microcontroller families.

The STM32F0xxxx and STM32F3xxxx devices embed a high-speed Inter Circuit

The configuration tool is implemented in the Microsoft Excel

www.st.com.

Before using the clock tool, it is essential to read the STM32 microcontroller reference

reference manuals.
