AMCC and Redpine Signals Collaborate on Next Generation Power Architecture-Based Embedded Wi-Fi Connectivity Solutions

Redpine's Lite-Fi(TM) product family offers best-in-class 802.11n with AMCC's PowerPC 405EX and EXr processors

SAN JOSE, Calif., April 14, 2008-- Embedded Systems Conference -- Redpine Signals, Inc., a leading developer of ultra low power multi-standard OFDM and MIMO silicon-based solutions, and Applied Micro Circuits Corporation (Nasdaq: AMCC - News), a global leader in embedded Power Architecture(TM) processing, optical transport and storage solutions, today announced the successful integration of Redpine's Lite-Fi(TM) 802.11n silicon solution on AMCC's PowerPC® 405EXr evaluation platform. The combination of Redpine's Lite-Fi(TM) and AMCC's PowerPC 405EXr enables a variety of embedded solutions that incorporate single-antenna ultra low power 802.11n connectivity at a lower cost than current 802.11b/g solutions. The partnership between Redpine Signals and AMCC also focuses on creating solutions for multi-antenna 3x3 802.11n-enabled systems such as enterprise access points (AP), routers and gateways that incorporate Redpine's MIMO 802.11n technology with an AMCC PowerPC 405EX processor.

Redpine's Lite-Fi product family offers differentiating performance and power advantages achieved through six years of research and multiple patents in all the relevant areas of architecture, signal processing, algorithms and low-power implementation. "Lite-Fi's interfaces and architecture are optimized for connectivity to embedded processors such as AMCC's PPC 405EX and EXr processors with minimal host overhead," said Mr. Venkat Mattela, Chief Executive Officer of Redpine Signals Inc. "Our partnership with AMCC forges complementary pieces of leading technology into consumer and enterprise products that stand out in functionality and performance," he said.

The PowerPC 405EXr, based on Power Architecture technology, is a price and performance optimized embedded processor for wireless access platforms including Wi-Fi access points, residential gateways and advanced set-top boxes. The 405EXr processor's scalability and rich feature set, including PCI Express and Gigabit Ethernet interfaces as well as USB2.0 On-The-Go and an integrated security engine that supports IPSec and SSL, provide for an ideal solution for current and emerging WLAN and WiMAX applications.

"The high level of integration in the PowerPC 405EXr reduces the external components required for next generation WLAN access designs, which drastically reduces system complexity and bill of material cost. The result is faster time-to-market and lower cost products," said Sam Fuller, Vice President Marketing at AMCC. "In particular, the 405EX and Redpine's Lite-Fi combine to provide an attractive platform for low cost and low power WLAN client applications such as wirelessly accessed printer servers and storage devices," he added.

The jointly developed solution for wireless client applications interfaces the Lite-Fi SoC to the 405EXr through a high-speed parallel interface, with a close-to-zero load WLAN driver on the PowerPC host. Lite-Fi incorporates a proprietary ultra low power multi-threaded layer-2 processor that not only provides a unique degree of protocol handling within the silicon but also provides power-efficient hardware offload of some critical layer-3 functionality, such as TCP checksum and security processing.

Redpine Signals and AMCC will display the joint solution at the Embedded System Conference in San Jose (CA) from 4/15 to 4/17 in AMCC's booth (#2010).
