The PAW3515DB 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 PAW3515DB is in a 8-pin optical package and comes with the resolution of 1000 counts per inch (CPI) and
the rate of motion up to 30 inches per second. It includes USB interface so that no mouse controller is needed to
interface through USB. The PAW3515DB can receive command and echo status or data format, both complete
Universal Serial Bus^® spec V2.0 and USB HID spec V1.11 compatibility. It is also a cost effective solution to
support USB Mouse.
