Agilent Technologies, Cypress Offer Optical Mouse Solution

2/19/2003 - Agilent Technologies Inc. (NYSE: A) introduced a new combination Universal Serial Bus (USB)-PS/2 reference design for lower cost, entry-level optical mouse products and other PC pointing devices. Agilent collaborated with Cypress Semiconductor to offer an optical mouse solution based on the Cypress CY763723 enCoReTM (enhanced Component Reduction) USB microcontroller and the Agilent ADNS-2620, the industry's smallest optical mouse sensor.

The new reference design includes a sample mouse with complete schematics, layout and firmware. It provides an easy-to-use platform for accelerated development of lower cost, entry-level optical mice, trackballs and integrated input devices.

"There is no question that users prefer the combination of pointing accuracy and trouble-free operation provided by optical mice," said Jason Hartlove, vice president and general manager of Agilent's Sensor Solutions Division. "Combining Agilent's smaller, lower cost optical navigation technology with Cypress' industry-leading USB microcontroller gives the optical mouse market a new lower price, faster time-to-market solution."

"This collaborative effort combines the best of both technologies from Cypress and Agilent to provide customers with a lower cost optical mouse solution while still providing the flexibility for customization," said Cathal Phelan, vice president of Cypress's Personal Communications Division. "This solution will help fuel the strong momentum of customers moving from the ball mouse technology of the past to the optical mouse technology of the present."

The new reference design kit continues the successful relationship between Agilent and Cypress, which began a year ago when the two companies announced their first joint reference design kit for high-performance optical mice, based on the Agilent ADNS-2051 sensor and the Cypress CY763723 enCoRe USB microcontroller.

The Agilent ADNS-2620 is an optical navigation system on a single chip, combining a lens, LED and assembly clip to form a complete mouse sensor solution. The sensor measures changes in position by taking thousands of digital pictures and mathematically determining the direction and magnitude of movement at a resolution of up to 400 counts per inch, and speeds up to 12 inches per second. The sensor's frame rate is programmable up to 2,300 frames per second. It is housed in a miniature 8-pin staggered DIP package.

The Cypress CY7C63723 enCoRe device features Cypress' proprietary M8 controller core -- the industry's smallest -- along with an integrated USB serial interface engine and transceiver, integrated EPROM plus RAM for storage and data buffering, and optimized output drivers for EMI reduction. Focusing on system cost reduction, Cypress' enCoRe family of USB microcontrollers employs an internal crystal-less oscillator and integrates several other components typically found off-chip in low-speed USB applications, such as pull-up resistors, wake-up circuitry and a 3.3V regulator.

The optical mouse reference design provides a complete resource for developers to customize their own designs. It is configured for a standard three-button mouse with flexible I/Os allowing expansion to five buttons. Data flows between the two chips across the SPI (serial peripheral interface) on the Agilent sensor. The design provides a single cable capable of connecting to a PC via a USB or PS/2 connector with an adapter. It will automatically detect the type of interface attached, enabling a USB- or PS/2-only mouse option. The EPROM-based microcontroller allows easy firmware modification, as well as storage of vendor and product IDs without an external EEPROM.

Agilent pioneered position sensing for mouse technology and supplies these products to all optical mouse manufacturers worldwide. More information about Agilent's optical mouse sensors is available at
