it was in a "we-muv" pedometer, but there is another chip on the other side of the board, under that weird black epoxy stuff. its still soldered on, since i want to find out how to use it first. do you have any ideas what it does? it doesn't look like ts connected to anything, but there are test contacts on the board around it. they say: -evdd -scl -sca and 2 of the pins look like they are connected by a orangy smd capacitor
I'll guess that the black blob has the processor & memory under it, the unidentified IC maybe interfaces to the pedo-mechanics? I couldn't find anything either...

Where did you get it, is it unmounted?
