On March 26, Linley Gwennap, principal analyst with The Linley
Group, will moderate a panel on Handset ICs at the Emerging Technology
Forum, a new track at the CTIA Wireless event in Orlando. His panel
will cover silicon trends and requirements for future wireless
media-driven handsets, processors, flash and DRAM, as well as silicon
integration roadmaps. For more information, visit the CTIA
Wireless website.
Broadcom
Targets HEDGE, EDGE Phones
At
3GSM, Broadcom announced two new handset processors for its
CellAirity lineup. The BCM21331 is a single-chip EDGE processor
with integrated RF and multimedia functions, reducing the cost
of 2.75G feature phones. The new chip, which is currently in
early sampling, integrates Broadcom's new all-CMOS radio technology,
which is also available in the standalone BCM2085. The CPU
is an unimpressive 208MHz ARM9, but using a new hardware video
accelerator, the chip is rated at 30fps QVGA for H.264, suitable
for midrange phones in 2008. The device is built in 65nm CMOS
to reduce cost and power.
The
new BCM2153 improves on the BCM2152, announced last year. Like
its predecessor, the 2153 is a 3G device that supports UMTS
and HSPDA at speeds of up to 7.2Mbps. EDGE support is also
provided for compatibility with 2G networks. The integrated
ARM11 application processor supports various smartphone operating
systems and delivers QVGA video resolution for H.263, H.264,
and MPEG4 as well as for mobile TV. The chip requires an external
radio subsystem. The 65nm device is in early sampling.
Broadcom
continues to invest heavily in the handset market, and its
R&D engine is hitting on all cylinders. The 21331 follows
the company's typical strategy of developing all key technologies
in CMOS and then combining them into highly integrated devices.
The 21331 can connect to Broadcom's new Bluetooth+WiFi+FM device
for greater integration and functionality. The 2153 is a higher-cost,
higher-performance device, but it will follow the same integration
path over the next few years. With a strong new product portfolio,
Broadcom is gaining share by out-executing its competitors.

MSM7225
Enables Lower-Cost Smartphones Also
at 3GSM, Qualcomm announced a new processor, the MSM7225, that
reduces the cost of its high-end MSM7000 family, designed for
smartphones. The 7225, which is due to sample in 3Q07, is a cost-reduced
version of the MSM7200/7200A. Like its predecessors, the 7225
supports a full range of 3G protocols including UMTS, 7.2Mbps
HSDPA, and 5.76Mbps HSUPA.
Like
the 7200, the new chip includes an ARM11 application processor
that can run Windows Mobile or Linux as well as Qualcomm's own
Brew software. The main difference is that the multimedia capabilities
of the 7225 are trimmed back to support wide QVGA video instead
of full VGA video. This change allows the company to position
the 7225 for smartphones that sell for less than $200.
Qualcomm
remains the only vendor offering a standard HSUPA baseband chip.
Although the 7225 won't be available for another couple of quarters,
the feature set is impressive. The processor is well suited to
a smartphone that requires high-speed connectivity, but other
vendors supply less-expensive solutions for basic EDGE and UMTS
smartphones. —Linley

TI
Reduces Cost of OMAP3
Also at 3GSM, Texas Instruments provided
more details on its Cortex-based OMAP3
family, rolling
out two
lower-cost variants
of the OMAP 3430
that was announced last year. The OMAP3
products announced to date are all standalone
application
processors that
do not integrate
a baseband processor. These chips are
the industry's first
to include
ARM's newest high-end CPU, known as Cortex-A8.
All are scheduled to reach production
by mid-2008.
The 3430 runs the CPU at 550MHz, providing
plenty of application power. The programmable
IVA2+
unit can
deliver XGA (1024x768)
video using a variety of codecs. An
integrated image processor supports
image sensors of up to 12Mpixels. The
chip also embeds a PowerVR SGX graphics
accelerator.
The
3430 provides
S-Video and composite
video outputs as well as parallel and
serial display connections. The 65nm
device is
currently sampling.
The 3420 is identical to the 3430 except
that it is restricted to VGA video
instead of XGA
video.
The 3410
is further
restricted to CIF video. The 3410
also lacks the image processor as
well as S-Video support. The 3420
is scheduled to sample in 3Q07,
with
the 3410 following one quarter later.
TI did not announce pricing, but
the new chips
are
intended to move the
OMAP3 architecture
into lower price points, replacing
the current OMAP2 products.
Leveraging
its close ties with ARM, TI has developed a range of application
processors based on the
Cortex-A8. These products
should
deliver better CPU performance than
competing
ARM11 products. By combining the
Cortex CPU
with a set
of acceleration
units, the
OMAP3 products provide impressive
multimedia performance with reasonable power dissipation.
TI's initial
experience with
the OMAP3 platform
has given it enough confidence to
cancel
its OMAP2 follow-ons in favor of
a broad family
of OMAP3
products. This change
simplifies future product development
for TI as well as
its many customers.

News
in Brief
AT&T's
announced support of Qualcomm's MediaFlo gives a big boost
to that mobile TV standard. Once seen as a weak competitor
to DVB-H and ISDB-T, MediaFlo
is gaining ground after endorsements
from AT&T and Verizon.
Qualcomm has spent an estimated
$800 million building
a MediaFlo network that covers
the United States
and is due to begin operating
in 2H07. The company hopes
that MediaFlo will dominate
the U.S. mobile-TV
market, giving the standard
a
leg up in Europe and Asia. —Linley
