    hi,
    If the EEPROM is connected to a MCU, use the ERAL command.

    Hello,

    As @ericgibbs said, use the ERAL command.
    See the pages 5 and 8 of the datasheet for more info.

    hi,

    Thanks
    How can i send ERAL command. Actually it is connected to one of FTDI chip. I can't have communication with it.
    So can you please explain me in details how should i make connection and write code for it.

    Till now i was accessing EEPROM by FT_PROG utility.

    Thanks for reply @ericgibbs, @bertus

    hi,
    How did you write the original data to the EEPROM.
    If the unwanted data in the EEPROM is not being used by the FTDI, the data will be automatically over written by the FTDI operation.
