ADBS-A320

Optical Finger Navigation

Data Sheet

Description

Features

The ADBS-A320 sensor is a small form factor (SFF) LED

illuminated optical ﬁnger navigation system.

 Low power architecture

 Surface mount technology (SMT) device

The ADBS-A320 is a low-power optical ﬁnger navigation

sensor. It has a new, low-power architecture and automatic

power management modes, making it ideal for battery-

and power-sensitive applications such as mobile phones.

 Self-adjusting power-saving modes for longer battery

life

 High speed motion detection up to 15ips

 Self-adjusting frame rate for optimum performance

The ADBS-A320 is capable of high-speed motion detection

– up to 15ips. In addition, it has an on-chip oscillator and  Motion detect pin output

integrated LED to minimize external components.

 Finger detect pin output

There are no moving parts which means high reliability

 Internal oscillator – no clock input needed

and less maintenance for the end user. In addition, pre-

cision optical alignment is not required, facilitating high

volume assembly.

 Selectable 250, 500, 750, 1000 and 1250 cpi resolution

 Dual 2.8V/1.8V or single 2.8V supply options

The sensor is programmed via registers through either a  Selectable Input/Output voltage at 2.8V or 1.8V

serial peripheral interface or a two wire interface port. It is

packaged in a 28 I/O surface mountable package.

nominal

 Serial peripheral interface (SPI) or Two wire interface

The ADBS-A320 is designed for use with ADBL-A321 lens.

The ADBL-A321 lens is the optical component necessary

for proper operation of the sensor.

(TWI)

 Integrated chip-on-board LED with wavelength of

870nm

Theory of Operation

Applications

The ADBS-A320 is based on Optical Finger Navigation

(OFN) Technology, which measures changes in position by

optically acquiring sequential surface images (frames) and

mathematically determining the direction and magnitude

of movement.

 Finger input devices

 Mobile devices

 Integrated input devices

 Battery-powered input device

The ADBS-A320 contains an Image Acquisition System

(IAS), a Digital Signal Processor (DSP), and a communica-

tion system.

Avago customers purchasing the ADBS-A320 OFN

product are eligible to receive a royalty free license to

our US patents 6977645, 6621483, 6950094, 6172354

and 7289649, for use in their end products.

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 x and y relative dis-

placement values.

The host reads the x and y information from the sensor

serial port if a motion interrupt is published. The micro-

controller then translates the data into cursor navigation,

rocker switch, scrolling or other system dependent navi-

gation data.

CAUTION: It is advised that normal static precautions be taken in handling and assembly

of this component to prevent damage and/or degradation which may be induced by ESD.
