    28 Pin SOIC

    What is the application? It may be a custom IC, as non of the strings come up in a quick datasheet search.

    For others to copy/pasta:

    Motorola Logo
    LSC527639CDW
    F005V10483
    0G22K
    CTCTAB0003

    In which case it's probably custom. Often car manufacturers will get an IC designed to specification, as it ends up being cheaper compared to using off-the-shelf parts.

    Would this be the masked custom IC they make so people can't hack their alarm frequencies?

    I am leaning in this direction. A few of the custom IC's I've seen haven't had that much information on them, but I guess if it is custom, they can say whatever they want.

    The fact tht it has memory chip close tell me it is uC.
    Could be a Motorola programmable one
