ADNK-5023-CY02
Optical Mouse Designer’s Kit
Product Overview
Description
Features
Avago Technologies has produced a new optical
mouse reference design kit. Based on the new Avago
Technologies ADNS-5020-EN small form factor optical
mouse sensor and the powerful Cypress CY7C63743
enCoRe USB microcontroller, this reference design
kit provides a low cost and yet, feature-rich solution
in one neat package.
• Complete optical mouse reference design kit
The Avago Technologies ADNS-5020-EN optical
mouse sensor, an 8-pin staggered dual inline
package (DIP), is based on an optimized architecture
with good navigation performance. It is able to
measure changes in position by optically acquiring
sequential surface images with auto frame rate
feature and mathematically determining the
direction and magnitude of movement.
The ADNS-5020-EN along with the ADNS-5100 lens,
ADNS-5200 clip and HLMP-ED80-XX000 form a
complete, compact optical mouse tracking system.
There are no mechanical parts, which means high
reliability 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 three-wire serial
port.
The Cypress CY7C63743 enCoRe is a revolutionary
chip that integrates numerous common
components, including breakthrough crystal-less
oscillator. The result is an overall reduction in board
components and reduced system cost. The EPROM
based microcontroller allows easy firmware
modification, as well as storage of Vendor and
Product IDs without an external EEPROM.
