Hello Srigo,

s>>oh by the way I am using the 16F77 which has no internal eeprom. the reason why I am asking this question is because the 16F77 does not have any internal eeprom. <<

Is there any way you can use a different chip? if you are going to go through the bother of purchasing external EEPROM, why not attempt to get a chip that is similar to the 16F77 that has EEProm?? Less circuitry, easier on pocket book, and the whole works.
