PAW3204DB-TJ3R
ULTRA LOW POWER WIRELESS MOUSE SENSOR
General Description
The PAW3204DB-TJ3R is a 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(AFC), this optical mouse sensor gains extra power saving
during mouse moving. With brand-new design Quick-Burst(QB) function, the controller can quickly read out
motion data for saving processing time and power.

Figure 3. Block Diagram
The PAW3204DB-TJ3R is a 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 wireless
computer mouse. It is based on new optical navigation technology, which measures changes in position by
optically acquiring sequential surface images (frames) and mathematically determining the direction and
magnitude of movement. The mouse sensor is in an 8-pin optical package. The current X and Y information are
available in registers accessed via a serial port. The word "mouse sensor", instead of PAW3204DB-TJ3R, is used
in the document.
With brand-new LED control technology, adaptive frame rate control (also known as AFC), the mouse sensor
gain extra power saving during mouse moving. The AFC servers position/speed detection and then mapping to
different frame rate. With lower frame rate, it leads to lower power consumption of the mouse sensor and LED.
The mouse sensor is featured with THREE-level AFC which is 2400/1200/800 frame per second.
A configurable Pin1 function provides flexible choice for the user to achieve different but general purpose in a
wireless mouse application. The mouse sensor provides THREE choices with Reset, Quick-Burst, and PD
functions. Note that default function is Reset.
With brand-new motion readout technology, Quick-Burst (also known as QB), the mouse controller could gain
extra power saving by quickly read out motion data. The QB servers TWO functions: (a) serial port synchronous,
(b) motion data dump. The controller could save serial port accessing time up to 75% by this function.
