You're in the wrong forum. This is the forum for asking for help about using the forum. I suspect that might be an 8-bitter, so you should be asking in that forum. Or maybe it isn't - it has an external bus and is in a 132-pin package. What are you trying to reverse-engineer (board # 279731-0181)?
That doesn't seem to be a Freescale product part number. The part in the photo doesn't even have the "Freescale" name or logo on it. A search of their site does find one document that lists that number as given, but I suspect it is a "private label mask part" made for a customer.
