adns-2080 low power optical mouse sensor data sheet description the pixart imaging adns-2080 is a low power, small form factor optical mouse sensor. it has a new low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications C such as cordless input devices. the adns-2080 is capable of high-speed motion detec - tion C up to 30 ips and 20 g. in addition, it has an on-chip oscillator and requires an external resistor to set the led current. the adns-2080 along with the adns-5110-001 lens, or adns-5120-002 lens, led clip, and hsdl-4261 ir led, or hlmp-eg3e-xxxxx red led form a complete and compact mouse tracking system. there are no moving parts and this translates to high reli ability and less maintenance for the end user. in addition, precision optical alignment is not required, facilitating high volume assembly. the sensor is programmed via registers through a two- wire serial port. it is housed in an 8-pin staggered dual in-line package (dip). features ? low power architecture ? small form factor ? programmable periods / response times and downshift times from one mode to another for the power-saving modes ? high speed motion detection up to 30 ips and 20 g ? external interrupt output for motion detection ? internal oscillator C no clock input needed ? selectable resolution of up to 2000 cpi ? operating voltage: as low as 2.1 v ? io reference voltage of 1.7 v to 3.3 v ? 2-wire serial port interface applications ? optical mice and optical trackballs ? integrated input devices ? battery-powered input devices all rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission. pixart imaging inc. e-mail: fae_service@pixart.com.tw 1
2 theory of operation the adns-2080 is based on optical navigation technol - ogy, which measures changes in position by optically acquiring sequential surface images (frames) and ma th - ematically determining the direction and magnitude of movement. the adns-2080 contains an image acquisition system (ias), a digital signal processor (dsp), and a two wire serial port. the ias acquires microscopic surface images via the lens and illumination system. these images are processed by the dsp to determine the direction and distance of motion. the dsp calculates the dx and dy relative dis - placement values. an external microc ontroller reads and translates the dx and dy informa tion from the sensor serial port into ps2, usb, or rf signals before sending them t o the host pc. pinout of adns-2080 optical mouse sensor pin name input/ output description 1 sdio i/o serial data input/output 2 led i led illumination 3 motion o motion interrupt output (default active low, edge triggered) 4 vddio i input/output reference voltage 5 sclk i serial clock 6 gnd i ground 7 vdd o regulator output 8 vdda i supply voltage figure 1. package outline drawing (top view) item marking remarks product number a2080 date code xyywwz x = subcon code yyww = date code z = sensor die source lot code vvv numeric all rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission. pixart imaging inc. e-mail: fae_service@pixart.com.tw pix a rt imaging inc. low power optical mouse sensor

4 overview of optical mouse sensor assembly pixart imaging provides an iges fle drawing de scribing the base plate molding features for lens and pcb align ment. the adns-2080 sensor is designed for mounting on a through-hole pcb, looking down. there is an aperture stop and features on the package that align to the lens . the adns-5110-001 and adns-5120-002 lens provides optics for the imaging of the surface as well as the illumination of the surface at the optimum angle. features on the lens align it to the sensor, base plate, and clip with the led. the led clip holds the led in relation to the lens. the led must be inserted into the clip and the leds leads formed prior to loading on the pcb. the leds recommended for illumination include hsdl-4261 ir led and hlmp-eg3e red led. figure 3. recommended pcb mechanical cutouts and spacing all rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission. pixart imaging inc. e-mail: fae_service@pixart.com.tw pix a rt imaging inc. low power optical mouse sensor
