AMCC Announces Industry's First Power Architecture Processor Specifically Targeting 802.11n and WiMAX Secure Wireless Access Points.

New PCI Express, Gigabit Ethernet and Integrated Security Features of the PowerPC 405EX Anticipate Requirements of Next Generation Access Points

SAN JOSE, Calif. -- Applied Micro Circuits Corporation (NASDAQ:AMCC) announced its next generation embedded processor for enterprise-class wireless access points at this week's Embedded Systems Conference(SM) in San Jose. The PowerPC[R] 405EX is based on Power Architecture[TM] technology and is optimized for the demanding requirements of 802.11n (Wi-Fi) and WiMAX(TM)-based wireless access points and similar embedded processing or network control applications.

"The 405EX offers major advancements in performance, bandwidth, security and multi-platform support for next generation access points based on the new 802.11n and WiMAX standards," said Sam Fuller, vice president of marketing at AMCC. "The increased performance, low power, and security acceleration capabilities of the 405EX processor will ensure AMCC's leadership position in this increasingly demanding market."

Based on a 90 nm CMOS[R] technology, the 405EX advances the state of the art in embedded processors for access equipment. The 405EX features dual PCI Express interfaces for connectivity to Wi-Fi or WiMAX radio chipsets or to other PCI Express-based chipsets. The internal bus architecture, security acceleration and integrated Gigabit Ethernet Media Access Controllers (MACs) ensure that the full bandwidth of 802.11n will be available. The high level of integration in the 405EX SoC reduces the external components required for next generation WLAN access point designs, which reduces systems complexity and bill of material cost resulting in faster time-to-market and lower cost products.

"Vendors continue to demand increased performance, lower power consumption and reduced costs from their component suppliers," noted Linley Gwennap, principal analyst of The Linley Group. "AMCC's 405EX meets these challenges using a new 90 nm version of the Power Architecture 405 core and increased integration of system functions. Wireless access-point designers in particular will welcome the processor's connectivity, very low power and excellent security options."

High Performance at Low Power

The Power Architecture core of the 405EX delivers a frequency range up to 667 MHz and is capable of delivering over 1,000 DMIPS of processing performance. A cross bar-based, on-chip system interconnect, provides low latency and increased bandwidth connectivity to a high-performance DDR2 SDRAM controller for main memory and to the PCI Express and Gigabit Ethernet interfaces. The sub 2 Watt typical power dissipation of the 405EX enables access points to utilize the 802.3af standard for Power-over-Ethernet. The benefit is obvious when considering that most access points are placed in ceilings or high on walls where access to AC power outlets is limited.

Security Acceleration

The 405EX features a best-in-class Turbo Security Engine that supports standard IPSec, SSL and DTLS security protocols. The Turbo Security Engine attaches directly to the processor bus for the fastest possible system throughput. The engine also features Public Key Acceleration and True Random Number Generation, as well as full header/trailer protocol processing. It is compliant with FIPS-140-2 and ANSI X9.17 Annex C.

Key Peripherals

The 405EX features two single lane PCI Express ports, each capable of delivering nearly 2.0 Gbps of bandwidth, and two integrated Gigabit Ethernet Media Access Controller (MAC) interfaces. Also included is a high-speed USB 2.0 On-The-Go port. A NAND Flash Controller and a full suite of Serial I/O ports, including UART, IIC, SPI and 32-bit external peripheral bus are additional key connectivity capabilities of the 405EX.

Support

Power Architecture processors from AMCC are supported by more than a hundred third-party vendors through the Embedded Tools Program. This support program includes compilers, debuggers, RTOS, emulators, logic analyzers and a full range of tools to assist manufacturers in developing products more quickly. In addition, AMCC will provide full evaluation kits as well as an 802.11n WLAN Reference Design to accelerate customers' time-to-market.

Availability and Pricing

The 405EX will sample in the third quarter of 2007. Distributor suggested resale pricing will start at $17 in 10Ku volumes. Further detail on the 405EX including technical specifications, can be found on the AMCC Website at www.amcc.com/embedded
