APPLICATION NOTE
STR71X CLOCK CONFIGURATIONS EASY SETUP
INTRODUCTION
This application note describes how to use the “STR71x_Calculation.xls” 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 “STR71x_Calculation.xls“ calculates all the working frequencies and shows the re-
lated register values for each peripheral.
Note: This application note doesn’t substitute the fact that it is mandatory to read the refer-
ence manual before the use of this tool.
