I don't know it. What package is it in? 24, 28 or 40 pins, DIP or skinny DIP, etc. Figuring out what pins are power and ground, and, if possible, oscillator input (resistor to one power rail and capacitor to the other is typical) would help, too. If you can, a scan of both side of the PCB would be useful.
