USB chips certified by USB Implementers Forum

Wireless USB host controller for PCI interfaces and Wireless USB device wire adapter (DWA) are among the first products to be certified by the USB Implementers Forum (USB-IF).

NEC Electronics announced that the its uPD720170 Wireless USB host controller for PCI interfaces and the uPD720180 Wireless USB device wire adapter (DWA) are among the first products to be certified by the USB Implementers Forum (USB-IF).

NEC Electronics' USB-IF-certified host controller and DWA make it easy and economical for designers to implement ultra wideband (UWB) wireless technology between USB peripherals and computers or consumer electronics products via a quick relay of data chunks based on Certified Wireless USB technology.

"NEC Electronics is at the forefront of delivering innovative solutions that will help to speed the adoption of the Certified Wireless USB specification, and we are continuing our commitment to the standard by having some of the first products to be fully certified", says Kunio Mori, General Manager, Peripheral Systems Division, NEC Electronics.

"These certified chips allow users to leverage the investment they have made in their current USB peripherals to make a seamless transition to the wireless standard".

NEC Electronics' uPD720170 host controller supports all eight data transfer rates -- from 53.3 up to 480Mbit/s.

The uPD720180 DWA chip provides the capability required by the Certified Wireless USB standard and also enables interoperability with current USB devices.

Designers can easily implement a complete system based on Certified Wireless USB technology by combining the two NEC Electronics chips.

Certified Wireless USB technology from the USB-IF is an extension to the current USB 2.0 standard.

It delivers data transfer rates up to 480Mbit/s, 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.

NEC Electronics has played a central role in making the current USB 2.0 standard one of the most successful interfaces in the history of personal computing.

Along with Intel and other industry leaders, NEC Electronics is a core member of the USB-IF, which developed and supports the USB specification.

Since launching volume production of USB 2.0 devices in 2000, NEC Electronics has shipped 100 million-plus units.

Samples of NEC Electronics' uPD720170 and uPD720180 Wireless USB devices are available now starting at US $20 each in sample quantities.
