CENTILLIUM COMMUNICATIONS DELIVERS FIRST AFFORDABLE SECURITY AND WIRESPEED VPN TO BUSINESS DSL MARKET

Centillium's Palladia™ 300 SecureDSL Chipset Combines ADSL Router, Networking and Security

FREMONT, Calif., January 29, 2002 - Centillium Communications, Inc. [NASDAQ: CTLM], innovator of broadband communications technology, today announced the newest member of its Palladia chipset family, the Palladia 300 SecureDSL Network Router. Centillium’s Palladia 300 product combines asymmetric digital subscriber line (ADSL), networking and security features into a single chipset, offering service providers business class security routers for small to medium size businesses.

Centillium’s revolutionary chipset fills an important market need for both carriers and Internet service providers (ISPs). By integrating the Palladia 300 chipset, original equipment manufacturers (OEMs) can deliver business class security and wirespeed virtual private network (VPN) routers that enable ISPs to realize enhanced revenues by offering managed security services to small and medium businesses.

Centillium Communications’ Palladia 300 chipset’s unique design includes security features such as a firewall, denial of service attack prevention and a secure wirespeed VPN. The security processor and ATM Adaptation Layer 5 (AAL5) accelerator (an accelerator that provides higher throughput) are hardwired into the chipset, ensuring consistent high data throughput and dependability required for a business network.

“Small businesses are increasingly reliant on the Internet and require an easy-to-use premises networking solution that integrates security, the single most important networking issue facing businesses today,” said Faraj Aalaei, chief executive officer and co-founder of Centillium Communications, Inc. “With the Palladia 300 chipset, OEMs can offer service providers a simple, secure network router with critical hardwired security functions and high-speed ADSL access services that meet the needs of small business users.”

The total size of the security market at the systems level is expected to grow despite slumps in other areas of the networking market. According to International Data Corp. (IDC), security services are expected to exceed $17 billion by 2004, with an annual growth rate of 25 percent.

“Security is a major issue for any company, but high costs are a key obstacle for small and medium businesses. Centillium Communications’ innovative Palladia 300 Secure Network Router chipset solves many of the problems for this market segment with its simplified design and resulting low costs with high performance to the end user,” said Jon Cordova, an analyst at Infonetics Research. “Centillium’s Palladia 300 Secure Network Router chipset is in an excellent position to take advantage of a growing ADSL market and help customer premise equipment (CPE) vendors integrate the security functionality in a simple form factor that end users are demanding.”
