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., Apr 03, 2007 (BUSINESS WIRE) — 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
