Targeting wireless keyboards and mice, as well as other wireless applications, the RadioDesk HID (Human Interface Device) platform from Chipcon AS is based on the company's SmartRF 04 CC2500 2.4GHz radio. This 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 RF protocol has been designed from the ground up to address the most important end user concerns facing wireless HID developers such as robustness, coexistence with WLAN, Bluetooth and other 2.4 GHz devices, long battery lifetime, and low latency, explained the company. Together with the blocking performance of the CC2500 radio, the protocol ensures one of the industry's best coexistence performance. The typical range of Chipcon's platform is 10m to 15m, which is much further than possible with older 27MHz solutions, added Chipcon.

"We believe that this platform will provide our customers with a differentiated solution and an enhanced user experience," shared Sverre Dale Moen, VP of Business Development. "Wireless keyboard/mouse developers looking to improve their products get a robust, low-cost, low-latency 2.4GHz 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. According to the press release, the total BOM cost is very competitive.

"Chipcon currently has the lowest power 2.4GHz radio on the market," commented Karl Torvmark, Product Marketing Director, Consumer Electronics at Chipcon. "Both with respect to low peak power consumption, possibility of burst-mode operation and less than 0.5ms start-up time, as well as its unique wake-on-radio functionality, the CC2500 is the best choice for power-constrained systems."

Other key components in the RadioDesk reference designs include Holtek Semiconductor's MCUs, Agilent Technologies' ADNS-2030 optical sensor, and 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.

Chipcon will provide the entire reference design, including PCB layouts and software source code to potential customers free-of-charge. The company added that the design is easy to customize, allowing customers to add value-added features to their own designs.
