APPLICATION NOTE

STR71X CLOCK CONFIGURATIONS EASY SETUP

INTRODUCTION

This application note describes how to use the âSTR71x_Calculation.xlsâ file which is intended

as a tool to assist in the configuration of the STR71x clocks and baud rates.

The STR71x microcontroller contains a variety of peripherals running at different frequencies.

Some peripherals have a prescaler to adjust their working frequency, but some others don't

and need a specific frequency to run correctly.

The file âSTR71x_Calculation.xlsâ calculates all the working frequencies and shows the re-

lated register values for each peripheral.

Note: This application note doesnât substitute the fact that it is mandatory to read the refer-

ence manual before the use of this tool.
