The PAW3504 supports X, Y, Z three axes, and L, R, M three buttons under USB mode. It is a CMOS process
optical mouse sensor single chip with USB interface that serves as a non-mechanical motion estimation engine
for implementing a computer mouse.
The PAW3504 is in a 14-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. It includes USB interface so that no mouse controller is needed to
interface through USB. The PAW3504 can receive command and echo status or data format, both complete
Universal Serial Bus^® spec V1.1 and USB HID spec V1.11 compatibility. It is also a cost effective solution to
support USB Mouse.
