Hi-
A buddy and I found this chip while dismantling a solar lamp. We are trying to reverse engineer the charging circuitry, but can't find any documentation about it. The closest we got was a semi obscure chinese website that had a hit for the first half of the name, said it was made by Freescale and the datasheet link turned up nothing. Neither does the Freescale website. Does anyone have any ideas?
Thanks

Rafael

    Just looking at those search results reveals that there are several package options from 8-pin to 16-pin TSSOP etc. This probably indicates that it is a microcontroller. If you know where the power and ground are connected on the chip and possibly some other signals you may be able to match it up with one from Freescale, possibly as HC08 or S08 family part.

    P.S. You won't find ID the part by it's number because it probably is a factory programmed part for the OEM. Why reverse engineer when you can find out what you need to do yourself.
