    Hello.. The part I'm trying to ID has the following markings.

    C3016 794C

    It is a 14 PIN DIP, in the handheld controller for a mini radio sub
    that worked in my fish tank, as seen here...

    It's the only IC, VDD goes to pin 9, while ground is pin 3.. how
    strange I thought.

    The buttons (NO), when pressed ground pins on the chip.
    Left = pin 14
    Right = pin 1
    Up = pin 5
    Down = pin 4
    Turbo Boost = pin 6

    This is how its laid out..

    right 1|----u-----|14 left
    (nc) 2| |13 (nc)
    GND 3| |12 R1 \
    down 4| |11 R1 / ---- C1 --- to ground.
    up 5| |10 -- R2 --- 49.8MHz XL
    boost 6| |9 VDD
    (nc) 7|----------|8 --- off to tx? transistors caps choak .. etc.

    So , some sort of coding , that modulates the carrier?

    Looks like the ATS302T (transmitter)and ATS302R (receiver) may have
    been a custom design for that radio control sub. Action Semiconductor
    in China don't list it in their products

    However Mobicon Electronic Components in HK have a data sheet ATS302TRX2C ATS302R Datasheet(English V1.02).pdf

    Note: you will probably need to copy and paste the
    (English%20V1.02).pdf part to the end of the URL. Also, it is a very
    slow server so be patient.
