    It might be custom part or relabeled part.

    If it is custom part, then finding datasheet will be impossible.

    If it is relabeled part, you can try using datasheets from similar products to figure out what is what.

    Welcome to AAC!

    EEPROMs in 6 pin packages don't have a write protect pin.

    Yes your right. 2 wire serial --- I just read that one clock pin and one data pin.
    I will never manage to hack that one. :-(
    After thinking about it can I read the data out of the registers in the chip and copy them to anouther chip?
