    I have bought a surplus of different electronic parts.
    I was not able to find any data sheets for these IC's. If anyone can help me, I would be very thankful!
    (Of course they could be custom specific circuits...???)

    XC411871P : Motorola 40-pin DIP (other text on the IC:STR512.01, 7D17E, CTZAD9617)

    TDA4557 : Philips 28-pin DIP (other text on the IC: 295130, DSD9822 7)

    TDA5652 : Siemens 20-pin DIP (other text on the IC: 9140)

    Thanks, Dan

    I think that you'll discover that this IC is a proprietary part, and Motorola/ONsemi/Freescale won't give you a datasheet for it.

    However, they might tell you who they manufactured it for.

    I'll hazard a guess that it's a pre-programmed microcontroller for an obsolete product, and would have little use except as a replacement for uC's in that product.
