PixArt Imaging Inc. PAW3205DB-TJ3T Wireless Optical Mouse Sensor 2. Block Diagram and Operation Figure 3. Block Diagram The PAW3205DB-TJ3T is a high performance and 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 PAW3205DB-TJ3T, 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.

PixArt Imaging Inc. PAW3205DB-TJ3T Wireless Optical Mouse Sensor 3. Registers and Operation The mouse sensor can be programmed through registers via the serial port. Also, the DSP configuration and motion data can be read from these registers. All registers not listed are reserved, and should never be written by firmware. 3.1 Registers Address Name R/W Default Data Type 0x00 Product_ID1 0x01 Product_ID2 0x02 Motion_Status 0x03 Delta_X 0x04 Delta_Y R R R R R 0x30 Eight bits[11:4] number with the product identifier 0xDX Upper Four bits[3:0] number with the product identifier Lower Four bits[3:0] number with the product version - - - Bit field Eight bits 2’s complement number Eight bits 2’s complement number 0x05 Operation_Mode R/W 0xB8 Bit field 0x06 Configuration R/W 0x02 Bit field 0x07 Image_Quality 0x08 Operation_State R R - - Eight bits unsigned integer Bit field 0x09 Write_Protect R/W 0x00 Bit field 0x0A Sleep1_Setting R/W 0x70 Bit field 0x0B Enter_Time R/W 0x10 Bit field 0x0C Sleep2_Setting R/W 0x70 Bit field 0x0D Image_ Threshold 0x0E Image_ Recognition R/W 0x0A Eight bits unsigned integer R/W 0xE5 Bit field 3.2 Register Descriptions 7 6 5 4 3 2 1 0 Product_ID1 PID[11:4] 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. 0x02 Motion_Status Bit 7 6 5 4 3 2 1 0 Field Motion Reserved[1:0] DYOVF DXOVF RES[2:0] Usage 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. 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.

Shown below are the bits, their default values, and optional values. Operation_Mode[4:0] “0xxxx” = Disable sleep mode “10xxx” = Enable sleep1 mode1 “11xxx” = Enable sleep2 mode2 “11100” = Force entering sleep23 “1x010” = Force entering sleep13 “1x001” = Force wakeup from sleep mode3 Notes: 1. Enable sleep mode, but disable automatic entering sleep2 mode. In this case, only 2 modes are available, normal mode and sleep1 mode. After 256 ms (typical) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until motion detected or wakeup bit asserted. Note that the entering time depends on the setting of Enter_Time register. 2. Enable sleep mode full function. In this case, 3 modes are available, normal mode, sleep1 mode and sleep2 mode. After 256 ms (typical) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until motion detected or wakeup bit asserted. After 20 sec (typical) not moving during sleep1 mode, the mouse sensor will enter sleep2 mode, and keep on sleep2 mode until motion detected or force wakeup to normal mode. Note that the entering time depends on the setting of Enter_Time register. 3. Only ONE of these three bits, slp2mu_enh/slp1mu_enh/wakeup, can be set to 1 at a single register write, others MUST be 0. After function works, the asserted bit will be reset to 0 by internal signal. 4. To force entering normal mode, clear Slp_enh/Slp2_enh bit when the mouse sensor is in normal mode; otherwise, in sleep mode, clear Slp_enh/Slp2_enh bit, and then assert Wakeup bit.

Shown below are the bits, their default values, and optional values. With Mot0Swk1 bit is clear, the MOTSWK pin is “level-sensitive”. The pin level remains low when motion has occurred; The mouse controller can read Motion_Status register, Delta_X register, then Delta_Y register sequentially to acquire motion data. After the mouse controller reads all data, Delta_X and Delta_Y are both zero, the pin level will be high (see Section7). With Mot0Swk1 bit is set, the MOTSWK pin is “edge-sensitive”. The pin will send a low pulse to trigger the mouse controller when the mouse sensor entering normal mode from sleep mode. The mouse controller can read Motion_Status register, Delta_X register, then Delta_Y register sequentially to acquire motion data (see Section7).
