LOGIC CORPORATION SUPPLIES ADSL MODEMS BASED ON CENTILLIUM COMMUNICATIONS' LEADING TECHNOLOGY TO RETAIL STORES IN JAPAN

USB ADSL Modems Available in Stores Now

FREMONT, Calif., September 24, 2001 - Centillium Communications, Inc. [Nasdaq: CTLM], innovator of broadband communications technology, today announced its joint effort with Logic Corporation, a leading telecommunications equipment provider in Japan, to supply Asymmetric Digital Subscriber Line (ADSL) Universal Serial Bus (USB) modems to Japanese retail outlets.

Centillium Communications' leadership role in the Japanese market has made ADSL modems available to consumers through local retail outlets. Service providers in Japan can now focus on speeding up marketing of ADSL service and other value added applications to consumers.

Logic's Stellar-Gate30U modem is one of the first USB modems on the market. Ease of installation and configuration has made USB modems a big success for Japanese consumers. Logic's USB modem, utilizing Centillium's Universal Optimizerä Annex C chipsets, will be marketed as part of its Stellar-Gate™ line. Centillium's Optimizer chipsets offer the end user "plug and play" options and support either Annex A or Annex C operation based on the choice of software drivers. Centillium's Annex C chipsets are the only proven solution to meet the special requirements for Japan, where Time Compression Multiplexing-Integrated Services Digital Network (TCM-ISDN) is widely deployed.

"When Centillium innovated a unique solution to overcome the existing problems with Japan's telephony infrastructure, it proved its commitment to Japan's broadband market," stated Masamichi Ishino, department manager of the business division for Logic. "Logic is excited about the opportunity to work with one of the pioneers in developing the Annex C standard and we believe that if our equipment contains a Centillium chip, we will maintain our position as an industry leader."

Along with leading Japanese telecommunications equipment manufacturers, Centillium helped to develop the Annex C technology that is the basis for DSL connectivity in Japan. Centillium is the only semiconductor company to come to market with a specialized solution for the Japanese infrastructure, which is based on Annex C.

"The combined efforts of Centillium and Logic in bringing ADSL modems to retail stores in Japan is extraordinary," stated Dori Braun, vice president of marketing for Centillium's Access Business Unit. "We are committed to bringing next generation broadband technology to the world and this partnership solidifies both our commitment and our leadership in the market."
