Wireless USB Host Controller and Device Adapter - µPD720170 - µPD720180 - NEC
Posted in USB, Wireless NetworkingOn Saturday, April 21, 2007
NEC announced the USB-IF certification of the µPD720170 Wireless USB host controller for PCI interfaces and µPD720180 Wireless USB device wire adapter. The new USB products help developers to implement wireless ultra wideband link between USB peripherals and computers or other consumer electronics products.

Application Example: µ PD720180 as Wireless USB HUB

The uPD720170 wireless USB host controller and uPD720180 wireless USB device wire adapter comply with the WiMedia MAC and wireless USB specification. Each device has one wired upstream-port and four wired downstream-ports. The chips are used with WiMedia UWB PHY that complies with WiMedia MAC-PHY interface specification.
Kunio Mori, NEC Electronics, said:
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…
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…
Certified Wireless USB is an extension to the USB 2.0 standard, targeted for next gen interface periperals and computers. It able to deliver data up to 480 Mbps, comparable to wired USB 2.0 connections, with a 10 meters maximum range.
