Block Diagram The PAW3502 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 PAW3502 is in a 14-pin optical package and comes with the resolution of 400/800/1000/1200 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 PAW3502 can receive command and echo status or data format, both complete Universal Serial Bus® spec V1.1 and USB HID spec V1.1 compatibility. It is also a cost effective solution to support USB Mouse.

USB Interface 5.1 USB Command Set Description (USB Descriptor) The USB HOST detects USB mouse device plug-in and assigns a new unique address to the USB mouse device, then asking USB mouse device for information about the device description, configuration description, and assigning a configuration value for USB mouse device during enumeration period. After enumeration, the USB mouse device is able to transfer motion and button value to the USB host.

PAW3502 USB Optical Mouse Sensor Single Chip 5.2 USB Data Report Format The USB report has two data formats, depending on boot or report protocol is selected. One kind of data format is the boot protocol used in legacy environment as 5.2.1. The other kind of data format is USB report protocol format which includes Z-wheel movement data in the fourth byte as 5.2.2. The Z-wheel is moved forward the fourth byte data is 01H, the Z-wheel is moved backward the fourth byte data is FFH, and the Z-wheel is idle the fourth byte data is 00H. 5.2.1 USB Boot Protocol for Legacy Operation Byte 1 Bit 0 1 2 3~7 0-7 0-7 Description 1 = Left button pressed 1 = Right button pressed 1 = Middle button pressed Reserved X data (D0 - D7).
