ADNK-5023-SP02
Optical Mouse Designer’s Kit
Product Overview Description
Features
Avago Technologies and Sunplus Technology Co. have joined forces to produce a new optical mouse reference design kit. Based on the new Avago Technologies ADNS5020-EN small form factor optical mouse sensor and the powerful Sunplus SPCP18A-13C microcontroller, this reference design kit provides a low cost and yet, featurerich 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 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 microcontroller, 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 adjustable resolution (500/1000cpi) via the application straps during power-on reset. 16-pin (3-buttons) or 18-pin (3/5buttons) 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.
