AMCC Wins Network Systems Design Conference Awards with Best in Show, Best Telecom Product Awards for Industry-Leading MISSION Platform.

SAN DIEGO -- -

AMCC Wrapped up a Banner Week with Nine Speaker Sessions, Two Coveted Product Awards and a Major Platform Introduction

Applied Micro Circuits Corporation (AMCC) (NASDAQ:AMCC) today announced that its popular MISSION(TM) platform received industry recognition when selected as both the Best Telecom Product and overall Best in Show by the Network Systems Design Conference (NSDC), held in San Jose, Calif., last week.

"All of our award winners offer superior and innovative technology," said Linley Gwennap, principal analyst of The Linley Group and program chairperson for NSDC. "But AMCC's MISSION platform stood out in the seamless integration of three chips to meet its customers' needs. The platform is well on its way to making a significant impact on the industry, making MISSION an outstanding choice as our Best in Show winner for 2004."

"AMCC's MISSION platform earned our award for Best Telecom Product because it combines the efficiency of dedicated standard products with the flexibility of programmable solutions," said Allan Armstrong, director of communications semiconductors at analyst firm RHK Inc. "MISSION supports channelization and common protocols like ATM and HDLC, and it is broadly applicable to a wide market, including access, multi-service switches and wireless. AMCC's design wins demonstrate that system vendors see the value of the MISSION solution."

At the conference, AMCC also formally introduced the next-generation member of the popular MISSION platform -- the MISSION Access(TM) chipset, which will be the catalyst for cost-effectively implementing this network transition closer than ever to access points where user traffic originates. MISSION and MISSION Access are products representing the collaborative efforts of AMCC's worldwide expert design centers.

A breakthrough, single-platform approach to delivering more features across multiple protocols and services, MISSION represents the next step for multi-service switches and core/edge routers, delivering Universal Port Services at Dedicated Port Economics(TM). The MISSION solution set includes the Evros (S1208) mapper, the Tigris (S4811) HDLC/ATM controller and the nP3700 network processor. The nP3700 utilizes AMCC's nP5(TM) technology, enabling developers to deliver extremely fine-grained control of subscriber traffic without impacting the ability to perform complex ATM and packet internetworking at media speeds.

MISSION Access is an OC-12 network processor and an integrated HDLC controller/channelized framer solution that will address the complex multi-protocol termination and inter-working functions required to interconnect the existing access technologies to the converged IP/MPLS service provider networks. This second-generation solution consists of the Amur (S1215), a framer and multi-protocol data processing product, the nP3705 integrated network processor and traffic manager, and the modular MISSION application software suite. MISSION Access has a fully software-compatible architecture to the original MISSION platform, which will allow customers to extend the features and benefits to their access product lines with only incremental R&D investment.
