Hi Waqar,

Those are pretty generic type chips. How you hook them up to a uC is pretty much determined by what you are trying to do.

Since you have the board in front of you and insist on reverse-engineering it, why don't you just get out your ohm-meter and buzz it out? With the connectivity determined, and the datasheets for the parts at hand, why things are connected as they are should be obvious.
