Darfon Selects Cypress’s WirelessUSB™ LP Radio System-on-Chip And enCoRe™ II MCUs For Next-Generation Wireless Mice


Elecom and BenQ Brand Mice to Deliver Extended Battery-life With Low-Power and Robust Performance of Cypress’s 2.4-GHz Solution

SAN JOSE, Calif., June 20, 2006 - Cypress Semiconductor Corp. (NYSE: CY) today announced that Darfon Electronics Corporation’s new generation of wireless mice will use Cypress’s WirelessUSB™ LP 2.4-GHz radio system-on-chip and enCoRe™ II flash microcontrollers. The mice will be marketed under the Elecom and BenQ brands. Darfon employed Cypress’s WirelessUSB LS and enCoRe USB devices for its previous generation of wireless mice for Elecom and BenQ.

Darfon’s innovative and award-winning wireless mice are recognized for their compact designs that allow users to store the receiver inside a smart storage compartment of the mouse while not in use. Darfon’s newest wireless mice leverage WirelessUSB LP’s low-power consumption for longer battery life and its robust interference immunity for excellent performance.

“The WirelessUSB LP device helped us deliver new mice with robust 2.4-GHz connectivity and low power consumption for extended battery life,” said Josh Tsai, product marketing director at Darfon. “In addition, Cypress’s whole product one-stop shop provided a complete reference design, development tools, and outstanding applications and technical support, allowing us to reduce the design cycle for these innovative, convenient mice, which are ideal for on-the-go end users.”

“We are pleased that Darfon has again selected Cypress’s WirelessUSB and enCoRe technologies to deliver end-to-end connectivity for their sleek, high-performance wireless mice,” said Matt Branda, senior product marketing manager of Cypress’s Human Interface Device Business Unit. “This design win is evidence that WirelessUSB LP offers the right combination of best-in-class interference immunity and low-power for next-generation wireless peripherals.”

About WirelessUSB LP
Cypress’s WirelessUSB LP offers an unparalleled feature set to enable superior interference immunity, low bill-of-materials (BOM) costs, higher data rate applications, and faster time-to-market for keyboards, mice, gaming devices, presenter tools, and remotes, as well as other simple, multi-point-to-point wireless applications. Featuring a highly integrated radio transceiver plus digital baseband on a single chip, it operates between 1.8 and 3.6 volts, using advanced power-saving techniques to extend battery life in devices such as wireless mice. WirelessUSB LP uses Cypress’s patented frequency agile Direct Sequence Spread Spectrum (DSSS) technology to offer best-in-class interference immunity for a 2.4-GHz radio system. This combination of low power consumption, interference immunity and low cost make it ideal for wireless HID applications. A photo of Cypress’s WirelessUSB LP can be downloaded at:"

About the enCoRe Family
Cypress’s enCoRe USB technology features a breakthrough crystal-less oscillator. By integrating the oscillator on-chip, an external crystal or resonator is no longer needed. Cypress has also integrated other external components commonly found in low-speed USB applications, including pull-up resistors, wake-up circuitry, and a 3.3V regulator. This integration results in shorter development cycles and lower system costs. In addition, the enCoRe family offers a Flash-based design that enables storage of wireless binding parameters as well as in-system reprogrammability and EEPROM emulation.
