Block Diagram 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. 3 All rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission.
