LITTLE LOW POWER WIRELESS MOUSE SENSOR
General Description
The PAW3204DB-TJDM, AKA PAW3204LL, is a high performance and little low power CMOS process optical
mouse sensor with DSP integration chip that serves as a non-mechanical motion estimation engine for
implementing a computer wireless mouse. With adaptive frame rate control, known as AFC, this optical mouse
sensor gains extra power saving during mouse moving.

PID[3:0]
VID[3:0]
The value in this register can’t be changed. PID[3:0] can be used to verify that the serial
communications link is OK.
VID[3:0] is a value between 0x0 and 0xF, it represents the chip version.

RES[2:0]
Motion_Status register allows the user to determine if motion has occurred since the last time it was
read. If so, then the user should read Delta_X and Delta_Y registers to get the accumulated motion. It
also reveals if the motion buffers have overflowed since the last reading. The current resolution is
also shown.
Notes
Reading this register freezes the Delta_X and Delta_Y register values. Read this register before
reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion
register is read a second time, the data in Delta_X and Delta_Y will be lost.

0 = No motion (Default)

Imgqa_th[7:0]
Image_ Threshold register allows the user to set image threshold. The mouse sensor calculates data to
Delta_X and Delta_Y registers when image quality (please see Image_Quality register) is larger than
image threshold.
Notes Field Name Description
Imgqa_th[7:0]
Image threshold: 0 (High recognition rate) ~ 255 (Low recognition rate). The
minimum level for normally working is 30. Default is 00011110.
