ADNB-3532
Low Power LED Integrated Slim Mouse Sensor
Data Sheet
Description
Features
The ADNB-3532 LED mouse bundle is a small form • Low power architecture
factor (SFF) LED illuminated navigation system. The
bundle consists of an integrated chip-on-board (COB),
LED mouse sensor ADNS-3530 and a SFF lens ADNS-
3150-001.
• Small form factor
• Surface mount technology (SMT) device
• Self-adjusting power-saving modes for longest battery
life
• High speed motion detection up to 20ips and 8G
• Self-adjusting frame rate for optimum performance
• Motion detect pin output
• Internal oscillator – no clock input needed
• Selectable 500 and 1000 cpi resolution
• Wide operating voltage: 2.7V-3.6V nominal
• Four wire serial port
• Minimal number of passive components
• Integrated chip-on-board LED
The ADNS-3530 is a low-power optical navigation sen-
sor. It has a new, low-power architecture and automatic
power management modes, making it ideal for battery-
and power-sensitive applications such as cordless input
devices.
The ADNS-3530 is capable of high-speed motion
detection — up to 20ips and 8G. In addition, it has
an on-chip oscillator and integrated LED to minimize
external components.
The ADNS-3530, along with the ADNS-3150-001 lens,
forms a complete and compact mouse tracking system.
There are no moving parts which means high reliabil-
ity and less maintenance for the end user. In addition,
precision optical alignment is not required, facilitating
high volume assembly.
Applications
• Optical mice
• Optical trackballs
• Integrated input devices
• Battery-powered input device
The bundle sensor is programmed via registers through
a four-wire serial port. It is packaged in a 16 I/O surface
mountable package.
Theory of Operation
The ADNS-3530 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.

ANDS-3150-001 Small form factor lens
The ADNS-3530 contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a four 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
displacement values.
An external microcontroller reads the Dx and Dy infor-
mation from the sensor serial port. The microcontroller
then translates the data into PS2, USB, or RF signals
0before sending them to the host PC or game console.
