I've been looking at the 16F877 and I can't really figure out why anyone would need an EEPROM when apparently it's just as easy to read from and write to the program memory.  Is it a matter of code protection (i.e., no danger of stomping on critical code)?  Any thoughts?


1,000,000 EEPROM write cycles versus 1,000 (or so) ROM write cycles.

You can't store 2 X 8 bit values in ROM (14 bits only)
Good for storing 2 ASCII bytes though
