Revision history
Rev Date Description
01 20081223 Initial version.
This application note / user manual is a complete update of a previous publication titled:
“Application note for the Philips Real Time Clocks PCF8563,73,83,93” which did not have
an official AN/UM number and is superseded by this document.
The contents were revised with lots of additional information added and errors in the
examples corrected. Additionally it includes information with respect to recently introduced
RTCs.
