San Jose, Ca., December 7th, 2005 - Continuing its drive as a technology provider into the rapidly growing WLAN products arena, Winbond Electronics Corporation is proud to announce the W89C37 as its latest member of the WinFi™ family of WLAN products. The W89C37 has received the WMM™ Power Save certification by the WiFi^® Alliance thanks to the new features of its latest generation MAC and baseband IC . As a successful participant of WiFi® Alliance plugfests, Winbond has also been selected as a client station in the WMM™ Power Save interoperability test- bed configurations.

This is an important milestone for a multi-faceted semiconductor company like Winbond. As the company successes in the PC, Consumer and Mobile electronics markets continue, Winbond's standard-setting Wireless LAN products are becoming indispensable ingredients for system developers.
