Figure1. Block Diagram

The PAN3203DI is a 27MHz wireless CMOS optical mouse single chip that serves as a non-mechanical motion

estimation engine for implementing a wireless mouse. PAN3203DI supports X, Y, Z three axes, and L, R, M, B4,

and B5 five buttons.

PAN3203DI is in a 24-pin optical package and comes with the resolution of 800 counts per inch (cpi) and the rate of

motion up to 28 inches per second. PAN3203DI embedded mouse controller in it so that no additional controller and

its component needed.
