UMC Joins the ZSP Foundry Program; Adds the ZSP400 Core to Its Library of Intellectual Property

• The ZSP® Foundry Program offers fabless IC designers a low cost of entry to the ZSP roadmap and faster time-to-market
  
• Robust, proven, ZSP cores offer best performance, lowest power, and cost efficiencies for wireless and multimedia applications
  
• Strategic collaboration meets growing demand for DSP technology in Asia

MILPITAS, Calif. - February 2, 2005 - LSI Logic Corporation (NYSE: LSI) today announced that leading semiconductor foundry UMC (NYSE: UMC, TWSE: 2303) is now offering the ZSP400 digital signal processor (DSP) core as part of its comprehensive portfolio of intellectual property (IP). By having access to the completed physical design of the ZSP400 qualified in UMC's proven 0.18-micron manufacturing process, small-to-medium-size fabless semiconductor companies benefit from significantly reduced risk, investment and time-to-market when developing solutions for wireless, audio and voice applications. UMC and LSI Logic plan to expand the offering to include additional ZSP cores and technologies later this year.

"Demand for a proven, robust DSP solution, like the ZSP cores, continues to be driven by the rapid growth of wireless, digital multimedia, and consumer electronics applications," said Ken Liou, director of the IP Development & Design Support division at UMC. "By offering the LSI Logic ZSP400 core, we are providing our customers with cost-effective access to a leading IP solution for their applications where DSP technology is a fundamental requirement."

The deliverables for fabless companies include a layout view, a fully characterized timing view, VMC swift model and testbench, test vectors and documentation for integration into a system-on-a-chip design. The core includes a tightly coupled memory subsystem, memory controller, debug unit, JTAG and clock control unit. The ZSP400 core is currently deployed in multiple chips and shipping in volume production in devices such as wireless phones, IP phones, gateways and multi-channel voice/data gateways.

"LSI Logic's agreement with UMC in joining the ZSP Foundry Program to offer the ZSP400 core as part of its IP portfolio is proof of the growing market presence of ZSP processing solutions in the burgeoning fabless IC market," said Tuan Dao, vice president of the LSI Logic DSP Division. "UMC is a global semiconductor manufacturing leader and we are pleased to be working together to enable faster time-to-market through ease-of-access to a world-class DSP technology."

In addition to the UMC partnership, LSI Logic has signed ZSP DSP licensing agreements in Asia with Datang Microelectronics, Huawei, UTStarcom, AVID Electronics Corp., Socle and ICC. World-class companies such as Broadcom, IBM, Conexant and VIA Telecom are also licensees of the ZSP architecture.
