— PRISM technology to be showcased in products from leading companies, including show partners Alcatel, AbsoluteValue Systems, Spectralink and Sybergen

IRVINE, CA, September 14, 2000 — Intersil Corporation (NASDAQ: ISIL), the world’s leading provider of silicon technology for Wireless Local Area Networks (WLANs), today announced that leading edge wireless networking systems based on its award-winning PRISM^® technology will be demonstrated at the upcoming Networld+Interop 2000 Conference in Atlanta, Ga., September 26-28.

At its booth (#4147) in the Georgia World Congress Center, Intersil will showcase products from leading wireless LAN vendors that illustrate the benefits of wireless networking everywhere we live and work, including the office, the home, and places with public access such as hotels and airports. Participating vendors include Alcatel (wireless home DSL gateway), AbsoluteValue Systems (Access Point for Linux OS), Spectralink (wireless Voice over Internet Protocol), and Sybergen (wireless ISP sharing software). And throughout the booth, customer products from Compaq, Cisco, Dell, Samsung, Sony, Casio, Hewlett Packard, Hitachi, Mitsubishi, Fujitsu and others will be displayed and demonstrated.

"The wireless LAN industry has made tremendous technological advances in recent years and today offers a multitude of low-cost, high performance products that can deliver wireless connectivity to virtually everyone — from business people to students to families at home," said Larry Ciaccia, vice president and general manager of PRISM Wireless Products at Intersil. "The increased focus on wireless networking systems at Networld+Interop each year affirms that this market is growing tremendously — and our demonstration illustrates many of the innovative products that are spurring this new wireless revolution."

Visitors to Intersil’s booth will witness live demonstrations of customer products performing Voice over Internet Protocol (VoIP), wireless transmission of DVD movies, interactive games, wireless Internet browsing and small wireless Internet appliances, including wireless digital camcorders, palmtops, laptops and Webpads. All products utilize Intersil’s 802.11- and 802.11b-compliant direct sequence spread spectrum (DSSS) technology.

Intersil will also participate in the Wireless Ethernet Compatibility Alliance (WECA) Pavilion (#1429). WECA, comprised of more than 30 WLAN industry leaders, certifies interoperability of Wi-Fi-compliant (IEEE 802.11b High Rate) products and promotes Wi-Fi as the global wireless LAN standard across all market segments. With cross-vendor interoperability assured, WLANs will be able to fulfill the promise of high-speed wireless mobile computing.

Adoption of PRISM WLAN Technology
Since introducing the PRISM WLAN chip set in 1996, over fifty companies have incorporated PRISM chips in more than 100 product designs. In a May 2000 report, the Cahners In-Stat Group called Intersil "the dominant force in the WLAN chip set marketplace with their PRISM chipsets holding the majority of market share." PRISM technology is designed to comply with the IEEE’s 802.11 global standard, and Intersil is a founding sponsor of the Wireless Ethernet Compatibility Alliance (WECA), whose Wi-Fi™ brand is a mark of compatibility for 802.11-based systems. PRISM chips are used in WLAN systems from industry-leading companies including Alcatel, Nokia, Siemens, Cisco, Compaq, 3Com, Dell, Nortel, Samsung, SpectraLink, Symbol, and Zoom.
