EEPROM has more read/write endurance cycles, something like 100,000. ----- Original Message ----- From: Barnaby Thieme To: Sent: Monday, March 05, 2001 3:25 PM Subject: (PIC): 16F877 -- Why an EEPROM? Hello. I'm considering moving from the PIC 16C65B and PIC 16C67 to a FLASH memory microcontroller. 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?
