Yes but that is for the program memory which does have a lower number of = reprogram cycles life. The data EEPROM portion is specified to many more = times reprogram cycles life. Check the data sheet, they are specified = differently. Coming back to the Flash Vs EEPROM debate, I think this is the area that = is used to distinguish between the two names now.=20 Flash as a terminology is used for the chips or area which have a low = number of programming cycles available, and is used for storing program = code.=20 EEPROM as a terminology is used for storage that has a high reprogram = cycle life and is used for storing data. These may not be the way the two terminology's started out, but it is = the way they now tend to be used (from my observation), irrespective of = trademarks and patents. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:" PIC only "[EE]:" engineering "[OT]:" off topic "[AD]:" ad's
