Agilent ADNK-2623
Optical Mouse Designer’s Kit
Product Overview
Features
• Complete optical mouse reference
design kit
• New Agilent ADNS-2620 optical
mouse sensor
• Precise optical navigation technol-
ogy for smoother and accurate
surface navigation
• No mechanical moving parts for
easy maintenance and high
reliability
Description
The Cypress enCoRe CY7C63723
is a revolutionary chip that
integrates numerous common
components, including break-
through crystal-less oscillator.
The result is an overall reduction
in board components and re-
duced system cost. The EPROM
based microcontroller allows
easy firmware modification, as
well as storage of Vendor and
Product ID™s without an exter-
nal EEPROM.
Agilent Technologies and
Cypress Semiconductor have
once again collaborated efforts to
produce a new optical mouse
reference design kit. Based on
the new compact Agilent
ADNS-2620 optical mouse sensor
and the powerful Cypress
CY7C63723 enCoRe™ USB
microcontroller, this reference
design kit provides a low cost
and yet, feature-rich solution in
one neat package.
• Programmable frame speed up to
2300 frames per second (fps)
•
High speed motion detector
with accurate motion up to
12 inches-per-second (ips) and
400 counts-per-inch (cpi) resolution
• Open serial interface for communi-
cation with microcontrollers
• Power conservation mode during
times of no movement
• Serial port registers for program-
ming and data transfer
This kit is connectable to a PC
via the USB or PS/2 ports. A
single cable with a USB connec-
tor and a PS/2 adapter is also
provided. The design automati-
cally detects the type of interface
is attached, allowing further
development of a USB or PS/2
only mouse.
The Agilent ADNS-2620 optical
mouse sensor is a new small form
factor, entry-level sensor built
with performance features. This
part enables more compact
designs and performance
enhancements. Housed in an 8-pin
package, this sensor has program-
mable features such as frame
speeds (from 500 to 2300 fps),
automatic power conservation
when idle, and LED strobing for
lower power consumption,
enhancing navigation perfor-
mance. With an open serial
interface, it can communicate
with most common

controller
• USB and PS/2 interface combina-
tion for PC connection
• Proprietary 8-bit RISC processor,
USB and PS/2-optimized inter-
faces for high system performance
• 8K Bytes of internal EPROM
provided to enable easy
customization of firmware and
lower cost
