ADNS-2080
Low Power Optical Mouse Sensor
Data Sheet
Description
The Avago Technologies 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 –
such as cordless input devices.
The ADNS-2080 is capable of high-speed motion detec-
tion – 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,
ADNS-5200 clip, and HSDL-4261 IR LED, or HLMP-EG3E
Red LED form a complete and compact mouse tracking
system. There are no moving parts and this translates to
high reliability and less maintenance for the end user. In
addition, precision optical alignment is not required, fa-
cilitating 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).

    ... 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 math- 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 ...

    ... Avago Technologies provides an IGES file 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 lens provides optics for the imaging of the surface as well as the illumination of the surface at the optimum angle ...

    ... Synchronous Serial Port The synchronous serial port is used to set and read pa- rameters in the ADNS-2080, and to read out the motion information. The port is a two wire serial port. The host micro-con troller always initiates communication; the ADNS-2080 never initiates data transfers. SCLK and SDIO may be driven directly by a micro-controller ...

  • Page 14

    ... Write Operation Write operation, defined as data going from the micro-controller to the ADNS-2080, is always initiated by the micro- controller and consists of two bytes. The first byte contains the address (seven bits) and has a “1” as its MSB to indicate write sequence. The second byte contains the data. The ADNS-2080 reads SDIO on rising edges of SCLK ...

    ... SRAD DELAY Note: The 500 ns minimum high state of SCLK is also the minimum SDIO data hold time of the ADNS-2080. Since the falling edge of SCLK is actually the start of the next read or write command, the ADNS-2080 will hold the state of data on SDIO until the falling edge of SCLK. ...
