ADNK-5023-SP02
Optical Mouse Designer’s Kit
Product Overview
Description
Avago Technologies and Sunplus Technology Co. have
joined forces to produce 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 Sunplus SPCP18A-13C microcontroller, this
reference design kit provides a low cost and yet, feature-
rich solution in one neat package.
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 mean 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 Sunplus SPCP18A-13C is a low speed USB microcon-
troller, specially designed for low speed USB-PS/2 combo
wired mouse with ADNS-5020-EN sensor application.
The chip supports up to 5 button modes and adjust-
able resolution (500/1000cpi) via the application straps
during power-on reset. 16-pin (3-buttons) or 18-pin (3/5-
buttons) PDIP and SOP packages are available.
This kit is connectable to a PC via the USB or PS/2 ports. A
single cable with a USB connector and a PS/2 adapter is
also provided. The design automatically detects the type
of interface is attached, allowing further development of
a USB or PS/2 only mouse.
