We are using the LPC11A14.


We want to get an estimate or spec on EEPROM endurance cycling.  The data sheet specifies an minimum endurance of 100000 cycles for EEPROM programing.  My question is, if we reprogram one byte, how many bytes get reprogrammed with it?


If we program one byte at a time using the IAP, are actually overwriting more bytes than that?


Is there an ideal way to use the IAP to achieve the maximum endurance time? e.g. start on a DWORD boundary, or 64 byte boundary etc, and program xx bytes.
