    I did not find your part number but doing a quick search makes me wonder if it is an Atmel part. Can you give us a picture so we can see the manufacturers logo?

    No logo.
    What I posted is what I see looking at the IC

    The Picture is correct Dodgydave.

    I like to know a programmer suitable to write to these little buggers.
    I have a firmware issue in a Samsung LCD Monitor.

    I believe programmer should be able to write the bin file from the PC

    If it is I2c and you have the firmware you could set up a pic to program it.
    Way back I got an early version on one of the TOPwin Universal programmers that cover just about all bases. Ebay 150763161122.
    I made my first I2c programmer using a pic from the Nigel Goodwin Tutorial.

    Hey guys. Will this do.

    I can write from PC and duplicate if needed. Right ?

    Doesn't the PICkit3 program I2C eeproms already?

    Just connect the wires to it (assuming you have a PICkit3). :)

    I have a PICkit3 but it does not seem to work.
    I need to check tht again.

    According to the Picmicro forums:-

    "Neither MPLAB 8 nor MPLAB X supports EEPROM programming using a PICkit 3. Look in the file "Device Support.htm" that is part of the MPLAB release notes to see which tools support specific serial EEPROMs."

    Even the 'Programmer-to-go' feature seems to require a recognizable device first?

    Thanks for that info. So the problem is in MPLAB?

    I'm sure I saw someone programming I2C EEPROMs with a PICkit3, maybe they used different software?
