Microsoft Demonstrates BLUE802™ Technology From Intersil and Silicon Wave During WINHEC 2002

World's First Dual-Mode Bluetooth™ and 802.11b Wireless Technology Solution Delivers Simultaneous Operation of Both Technologies in One Device

Irvine and San Diego,CA - April 22, 2002 - Intersil Corporation (NASDAQ: ISIL), the world's leading supplier of silicon for Wireless Local Area Networks, and Silicon Wave, Inc., a world leading supplier of silicon for Wireless Personal Area Networks, today announced their new Blue802™ technology that Microsoft officials demonstrated at WinHEC 2002 last week.

Intersil and Silicon Wave have jointly developed the Blue802 technology that enables customers to fully integrate both Wi-Fi (IEEE 802.11b) and Bluetooth wireless technologies on a single platform. Implemented in the world's first dual mode chip set solution available to the market, the highly integrated Blue802 solution can be embedded into products such as notebook PCs, portable devices and access points to provide simultaneous operation of Bluetooth and Wi-Fi wireless functionality with optimal throughput and without interference. Using this technology, customers are expected to begin shipping mini-PCI cards for notebook PCs in volume in the third quarter this year.

"As businesses and consumers further recognize the tremendous benefits of wireless connectivity, users want the ability to perform an array of applications that utilize both Wi-Fi and Bluetooth automatically," said Jawad Khaki, vice president of Microsoft's Windows Networking and Communications. "We're committed to providing support for these technologies in our product portfolio and are pleased to see the progress Intersil and Silicon Wave have made in integrating these complementary technologies."

"Wi-Fi and Bluetooth are complementary wireless technologies that will collectively eliminate wires and cables from the computing experience," said Larry Ciaccia, vice president and general manager of Intersil's Wireless Networking business. "We're confident that our work with Silicon Wave delivers the promise of a truly wireless environment by untethering applications neither technology could achieve alone. We're thrilled to see the enthusiasm for this technology by an industry leader like Microsoft."

"Combining the proven competencies of Silicon Wave and Intersil, two industry-leading silicon developers, has created the world's first practical solution integrating two of the most popular wireless technologies today," said David Lyon, CEO of Silicon Wave. "Blue802 technology demonstrates the innovation both companies have brought to this successful implementation enabling peaceful coexistence of Bluetooth and Wi-Fi wireless technologies."

About Blue802 Technology
Silicon Wave and Intersil have developed Blue802 technology, a unique collaborative real-time communications interface at the MAC layer that is transparent to the notebook PC or portable device user. Data can be transmitted without interference while optimizing system throughput, range, and responsiveness. This enables Bluetooth applications such as mouse, keyboard, printing, file transfer and portable device synch to run at the same time the user is connected to the network over Wi-Fi. For more information about the Blue802 technology visit Intersil and Silicon Wave at Networld + Interop on May 7-9, 2002 in the Wi-Fi Pavilion, Booth #343.
