PAW3204LU-TJDU
SMD-TYPED ULTRA LOW POWER WIRELESS MOUSE SENSOR
General Description
The PAW3204LU-TJDU is a SMD-typed high performance and ultra 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, AKA AFC, this optical mouse sensor gains extra
power saving during mouse moving.

Product_ID2
76543210
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.

Motion
Reserved[1:0]
DYOVF DXOVF
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.
Field Name Description
Motion
Motion since last report
0 = No motion (Default)
1 = Motion occurred, freeze motion data in Delta_X and Delta_Y registers
Reserved[1:0] Reserved for future use
DYOVF
Motion Delta Y overflow, ΔY buffer overflowed since last report
0 = No overflow (Default)
1 = Overflow has occurred
DXOVF
Motion Delta X overflow, ΔX buffer overflowed since last report
0 = No overflow (Default)
1 = Overflow has occurred
RES[2:0]
Resolution in counts per inch
000 = 500
001 = 650
010 = 750 (Default)
011 = 1000
100 = 1300
101 = 1500

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 20. Default is 00010100.
