    how to erase an eeprom

    If you can only program this eeprom then program all locations (from 0 to 32767, or from 0000h to 7FFFh) with FFh, and this will be equivalent to erasing it ..
    As an alternative:
    The entire device can be erased at one time by using a 6-byte software code.
    Here is the explenation on how to do it:
