NEC Electronics' device wire adapter LSI chip

NEC Electronics Corp. and its subsidiaries in the Americas and Europe have announced the availability of samples of a new device wire adapter (DWA) LSI chip to enable the connection of wired USB peripherals, such as a mouse or printer, to systems based on the Certified Wireless USB specification.

The ?PD720180 DWA chip, which complies with the USB-IF Certified Wireless USB specification, makes it easy and economical for designers to implement the relay of signals between wired USB peripherals and computers or consumer electronics products based on Certified Wireless USB technology.

The new device provides the functionality required by the Certified Wireless USB standard formulated by the USB Implementers Forum (USB-IF). The device also enables interoperation with current USB devices. Designers can easily implement a complete system based on Certified Wireless USB technology by combining the new DWA chip with the company's previously announced ?PD720170 host controller chip, NEC Electronics explained.

Hub function
The new chip also provides a hub function that allows users to connect up to four USB devices wirelessly. This feature makes it easy to configure optimum systems to meet different user requirements.

Certified Wireless USB technology from the USB-IF is an extension to the current USB 2.0 standard that has been hailed as the next-generation interface for computers and multimedia consumer electronics. Certified Wireless USB technology delivers data transfer rates up to 480Mbps, comparable to wired USB 2.0 connections, with a maximum wireless communications range of up to 10m.

Unwiring the cable connection frees users from having to make cumbersome and unsightly wired connections to enjoy high-speed data access and allows users to connect their devices freely wherever they want to use them. Certified Wireless USB technology will make it possible to expand the range of applications for computers and digital entertainment devices and encourage the discovery of new ways to enjoy digital media.

"Like the wired specification, Certified Wireless USB technology provides data transfer rates up to 480Mbps, fast enough to transfer the audio data for one song in less than a second," said Kugao Ouchi, general manager of digital consumer and connectivity strategic business unit at NEC Electronics America. "With our new adapter chip, users will be able to leverage the investment they have made in their current USB peripherals to make a seamless transition to the wireless standard, a crucial component for increasing acceptance of this interface technology."

The ?PD720180 DWA chip is currently available and is priced at $40 each in sample quantities. Volume production is scheduled to begin in December 2006. Pricing and availability are subject to change.
