Atmel Announces Second Generation Voice Over IP Chip for Wi-Fi Based Phones

San Jose, California (ots/PRNewswire) -

Atmel(R) Corporation (Nasdaq: ATML) formally announced today its
second generation Voice over IP (VoIP) chip, designed for 802.11a/g
wireless VoIP applications. The AT76C902 runs the VoIP Session
Initiation Protocol (SIP) stack, uCLinux(TM) operating system
software, and firmware enabling 802.11a/g (Wi-Fi(R)) and voice
compression and decompression all on a single chip. The AT76C902
consists of an ARM946(TM) processor for VoIP call control,
authentication and signaling functions, and two subsystems -- an
ARM7(TM) and 802.11a/g Media Access Controller (MAC) that implements
the 802.11a/g protocols, and a TEAK TeakDSPCore(TM) and integrated
voice codec for voice processing functions. Additionally, hardware
security accelerators offer on-the-fly encryption, decryption and
authentication support for AES, DES/3DES and TKIP, supporting WPA and
WPA2 -- Personal and Enterprise. Based on this architecture, as well
as engineering focus on power consumption, the AT76C902 is able to
achieve world-class talk and stand-by times.

Atmel's AT76C902 supports Wi-Fi Multimedia (WMM) and WMM Power
Save modes. WMM adds Quality of Service (QoS) capabilities to Wi-Fi
networks. WMM Power Save is an improvement to the 802.11e amendment
adding advanced power management functionality to WMM. WMM Power Save
is based on Unscheduled Automatic Power Save Delivery (U-APSD),
which, like WMM, is based on Enhanced Distributed Channel Access
(EDCA). U-APSD is a solution well suited for dynamic environments
where Wi-Fi is generally deployed and allows clients supporting
U-APSD to download all or some of the frames buffered by the access
point during unscheduled service periods. By supporting U-APSD and
Scheduled APSD (S-APSD), solutions based on Atmel's AT76C902 have
talk times of over six hours and stand-by times of over 220 hours on
a 900 mA battery. This is achieved even when the access point it is
connected to does not support WMM APSD.

The best solution for customers requiring high-quality voice,
stable performance and the longest talk/standby times in the market
(for a given battery size) is to deploy AT76C902-based Wi-Fi phones
along with Atmel's AT76C520-based access points. If a WLAN exists and
the access points cannot change, then the AT76C902 terminals will
produce the best results. Phones based on Atmel's AT76C902 have been
tested in-house against all the access points within the Wi-Fi test
plan and interoperate with no issues. If the terminals are deployed
and they support APSD but the access points can be replaced, the
AT76C520 will produce the best results for the existing terminals.

"Atmel is very excited about the introduction of this chip. The
AT76C902 has been very well received in the market and has been
selected by several major Tier-one OEM makers," said Richard Bisset,
Product Marketing Director of Atmel's Multimedia and Communications
Product Group. "Because of its architecture, the AT76C902 provides
the ability to perform multiple functions that would otherwise not be
able to be performed by a single-CPU-based processor. By moving to
the uCLinux operating system software, we are able to provide our
customers a feature-enriched software package in source code format
without any licensing or royalties."

To facilitate quick time-to-market and reduce engineering costs, a
complete development kit (AT76C902-DK) including Atmel's AT76C902
VoIP processor, AT76C517.11a/g baseband, flash memory and the Airoha
single-chip 802.11g RF transceiver with integrated Power Amplifier
(AL2236) is available to qualified customers. The AT76C902-DK also
includes a miniature-sized module design containing all critical
sections of a stand-alone wireless VOIP phone. Included with the kit
are complete schematics, bill of materials, a reference design,
Gerbers and software. The VoIP SIP stack is licensed from
Radvision(R) (announced on May 15, 2006). Other software provided is
the firmware for the 802.11a/g, the voice codecs and the uCLinux
operating system.

Price and Availability

The AT76C902, packaged in a 208-pin BGA, is released to
production. Pricing for the AT76C902 starts around US$18 at 25K
units.
