    Hi..

    I am working on a project utilizing a discarded coffee pot and I would like to be able to salvage as many components as possible from the original unit. I need a 7-segment display and driver IC in my project and this coffee maker just happens to have both. Unfortunately, I cannot for the life of me find any info on either.

    The coffee maker itself is a wally word special, model # 106581

    The driver IC has:

    59723
    Philippines

    printed on one side and:

    WT2232
    0010CAG

    printed on the other. they have it mounted on it's side with one side going to the main board and the other side going to the LED display board. From my searches, I was able to find that (I think) the chip is a real-time clock processor, but I found a lot of ICs with that same number - all having different functions listed - none having datasheets. RTC just seems to be the best fit for this application...

    The 7-segment LED display module is affixed to a circuit board with:

    Sanyo 1008C

    printed on it. I could pin out the display board if I absolutely HAVE to, but I'd rather not have to.

    Any help that anyone can give would be greatly appreciated!

    Welcome to what is likely OEM renumbered parts, I would personally give up on the driver IC unless you stumble upon something useful or reverse engineer the circuit and figure it out...

    Pinning out the 7 segment is the easiest way to figure it out (and confirm)... Just get yourself a CR2032 coin battery at the dollar store and start touching legs, chances are it's the same pinout of any other 7 segment of the same layout so you can get a head start by just finding a similar laid out 7 segment... With the C suffix designation a guess could be taken it's common cathode...

    Yeah, that's what I figured. Turns out the display is just as wonky. I wound up stripping it out, too, and using a different display and driver IC. Thanks...
