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

San Jose, CA — Embedded Systems Conference — April 14, 2008 — 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], a global leader in
embedded Power Architecture™ processing, optical transport and storage solutions,
today announced the successful integration of Redpine’s Lite-Fi™ 802.11n silicon
solution on AMCC’s PowerPC® 405EXr evaluation platform. The combination of Redpine’s
Lite-Fi™ 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).

Wi-Fi CERTIFIED™
Redpine’s Lite-Fi™ solution is Wi-Fi CERTIFIED for 802.11n draft 2.0 by the Wi-Fi
Alliance.

"802.11n draft 2.0 is an advanced standard for delivering increased throughput,
improved range and Quality of Service (QoS) for enhanced multimedia capabilities. In
achieving Wi-Fi CERTIFIED for 802.11n draft 2.0, Redpine Signals has demonstrated
its commitment to ensuring industry interoperability and the best experience for
Wi-Fi users," said Wi-Fi Alliance Senior Director, Karen Hanley.
