    ??? The 93c4x is an eeprom... But that number doesn't compute... Are you sure that's the number??

    Hi MS,

    That chip does not exist. Have you copied the part number correctly. Your post title and the part you are asking about are not consistent.

    The closest chip from the Atmel range is the, AT93C46: http://www.atmel.com/Images/Atmel-5193-SEEPROM-AT93C46D-Datasheet.pdf

    Renewing an old thread here;

    Spec already posted a link above which is what you have.
    Actual package marking can be confusing; Look at page 14 of the datasheet for the 8-lead PDIP package;

    I am using MiniPro Programmer. Its not read the chip o the programmer, But its working in the hardware.

    When the time of programing, its shows an error.

    I dont understand "ATMLU934 2EB" so, what is the actual number of the Chip. I dont recoganise the chip number with the help of the datasheet. :(

    What I do?

    Regards Manoj

    OK, One more time;

    Instead of attempting to explain the ATMEL's convoluted datasheet, the following is what you have;

    Based on your posted picture, provided it is NOT a copycat, the main significant number here is the second row; 2 F B 1

    It denotes an obsolete ATMEL two-wire, serial 512K EEprom. Part number AT24C512B.
    It was originally designed to ONLY operate between 1.8~3.6V Vcc !
    However, date code of (814) week 14/2008 or later added support for 5V operation.-- You have a 934 code which is fine with 5V. ...whew

    I am not familiar with your programmer but AT24C512B algorithm must be supported for programming.

    Hello vteh

    How it can be Erase with the programmer? The Erase Function is not working in the software for this AT24C512B.
