The PAW3512DK 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 PAW3512DK is in a 12-pin optical package and comes with the resolution of 1000 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 PAW3512DK 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.
