Cypress’s Fully-Integrated PRoC™ LP Powers Darfon’s Ultra-Small Micro Dongle For Wireless Mice


Low-Power Programmable-Radio-on-Chip Delivers Robust RF Connection in a Single Package

SAN JOSE, Calif., April 2008 - Cypress Semiconductor Corp. (NYSE: CY) today announced that Darfon Electronics Corp. (Darfon), a leading manufacturer of PC peripherals, has selected Cypress’s PRoC™ LP programmable radio-on-chip for a new ultra-small micro dongle for wireless mice. The micro dongle, roughly the size of a U.S. dime, uses the fully-integrated CYRF69213 PRoC LP device to deliver flawless, low-power wireless connectivity to Darfon’s mice.

Unlike most wireless USB dongle designs, Darfon’s micro dongle targets the mobile notebook market by protruding less than 5mm from a computer, minimizing the risk of damage from accidental contact. PRoC LP provides the dongle with a dual-role single-chip solution, integrating Cypress’s 2.4-GHz WirelessUSB™ LP radio and enCoRe™ II microcontroller in the same package. Cypress’s ultra-low power wireless technology prolongs battery life for Darfon’s mice. The industry-leading interference immunity of Cypress’s AgileHID™ protocol allows the mice to operate uninterrupted in the home environment, where the 2.4-GHz spectrum is crowded with signals from Wi-Fi, microwaves, cordless phones and other devices.

“On top of the integration that enables the ultra-small size of our dongle, Cypress’s PRoC LP delivers the reliable wireless communication and low power consumption our OEM customers demand,” said Peter Cheng, vice president of the Human Input Devices Division at Darfon. “PRoC LP also simplified our design process and improved our time to market.”

“Darfon’s micro dongle mouse demonstrates the potential of seamless component integration in wireless Human Interface Devices, as its small form factor opens up the possibility of a virtually ’inside-the-box’ wireless peripheral connection for notebooks or desktops,” said Carl Brasek, director of the Wireless/HID Business Unit at Cypress. “PRoC LP enabled Darfon to design a very compact device without having to sacrifice style, practicality, battery life or reliability.”
