Chipcon Launches the RadioDesk™ Reference Design and Protocol for the Wireless Keyboard/Mouse Market

Apr 20, 2005

OSLO, Norway (April 20, 2005) -- Chipcon AS, a leading provider of high-performance, low-cost, low-power RF-ICs today launches its RadioDeskTM HID (Human Interface Device) platform. Based on Chipcon's state-of-the art SmartRF®04 CC2500 2.4 GHz radio, the platform consists of a ready-for-production keyboard and mouse reference design utilizing Chipcon's RadioDesk advanced adaptive frequency-hopping (AFHSS) RF protocol. The RadioDesk platform targets wireless keyboards and mice, as well as applications such as wireless game pads for PC gaming, remote controls for Media PCs, and wireless presentation controls.
The RadioDesk RF protocol has been designed from the ground up to address the most important end user concerns facing wireless HID developers: robustness, coexistence with WLAN, Bluetooth and other 2.4 GHz devices, long battery lifetime and low latency. The RadioDesk protocol is based on adaptive frequency hopping. Together with the excellent blocking performance of the CC2500 radio, the protocol ensures the industry's best coexistence performance. The typical range of Chipcon's platform is 10-15 meters, much further than possible with older 27 MHz solutions. There is a clear trend in the market towards 2.4 GHz, both among design houses and consumers.
"We believe that this platform will provide our customers with a differentiated solution and an enhanced user experience," says Sverre Dale Moen, Chipcon's VP of Business Development. "Wireless keyboard/mouse developers looking to improve their products get a robust, low-cost, low-latency 2.4 GHz solution with long battery lifetime. RadioDesk fulfils all of their requirements," he added.
The RadioDesk keyboard/mouse platform is a production-ready design consisting of a wireless keyboard, a wireless optical mouse and a very small form-factor USB dongle. The total BOM cost is very competitive. Chipcon claims to have the most cost-efficient 2.4 GHz solution on the market.
"Chipcon currently has the lowest power 2.4 GHz radio on the market," says Karl H. Torvmark, Product Marketing Director, Consumer Electronics at Chipcon. "Both with respect to low peak power consumption, possibility of burst-mode operation and less than 0.5 ms start-up time, as well as its unique wake-on-radio functionality, the CC2500 is the best choice for power-constrained systems."
The reference design is built around the CC2500 2.4 GHz RF transceiver. Other key components in the RadioDesk reference designs include Holtek Semiconductor MCUs, the Agilent Technologies ADNS-2030 optical sensor, as well as an advanced chip antenna from Fractus. The USB solution is compliant with the USB HID specification and is completely plug-and-play without the need for any custom drivers.
"The RadioDesk platform is part of Chipcon's commitment to provide low-cost, high performance solutions to the developers of consumer electronics. The availability of a finished, production-ready design will shave months off the time-to-market for Chipcon's customers," says John Fjellheim, Chipcon's VP Worldwide Sales.
Chipcon will provide the entire reference design, including PCB layouts and software source code to potential customers free-of-charge. The design is easy to customize, allowing customers to add value-added features to their own designs. Customers should contact their local Chipcon representative to receive these materials.
