SAA3018 remote handset chip.
No luck (so far) with Google, I tried with & without the 'P' suffix, and
also tried a general search for "remote control" in the hope a datasheet would turn up in an online repository somewhere. There were a few links to a "SAA3018" datasheet - but the actual file turned out to be for the SAA3010. Hand tracing is going to be difficult, the PCB has 3 layers of resist: first layer - solder resist, second layer - carbonisation for buttons resist and third layer for track bridging links. The remote has been wet, the top layer of resist has blistered and peeled, and taken the bridging links with it. The 3010 datasheet I found has too many pins - The 3008 has the right number of pins, and the pinout matches what little of the circuit I was able to trace. No doubt the 3008 & 3018 differ mainly in features and functions. The correct datasheet would be nice - but at this point I could probably get more info from example schematics of remotes that use the SAA3018. Thanks for any help. |
