California Micro Devices Launches New Serial Interface Display Controller for Wireless Handsets

MDDI Dual Display and Audio Controller Offers Unprecedented Cost,
Footprint and Functionality MILPITAS, Calif., Oct. 4
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today unveiled a dual display and audio controller for wireless
handsets that incorporates the VESA Standard Mobile Display Digital
Interface (MDDI) link, which is fully compatible with QUALCOMM's
Mobile Station Modem(TM) (MSM(TM)) chipset solutions. The new
CM5100 features a fully compliant, MDDI based serial client, an
integrated display controller with embedded memory that supports
primary thin film transistor (TFT) liquid crystal displays (LCDs)
with resolutions up to QVGA (320x240) and secondary displays with
up to QCIF+ (176x220) resolution. The CM5100's unique architecture
is optimized for use with today's most advanced TFT LCD modules
that feature drivers integrated directly on the display glass and
also allows the use of low cost, RAM-less drivers for
non-integrated display modules. In both cases, CM5100-based
implementations result in a significantly smaller footprint and
lower solution cost than competitive solutions. Additionally,
California Micro Devices' CM5100 is the first integrated display
controller with an integrated MDDI compliant audio controller and
features advanced audio and video synchronization capabilities.

According to Mike Concannon, vice president of strategic products
for QUALCOMM CDMA Technologies, "The new CM5100 controller delivers
the complete value proposition of MDDI based display interfaces,
including reduced signal count, low power and improved ease of
design, all in a small form factor. With support for audio streams
over the MDDI interface, the CM5100 offers designers the ability to
take full advantage of the functionality defined in the MDDI
standard." Mobile Display Trends With the emergence of advanced
multimedia capabilities in mobile handsets, data rates between the
handset's host processor and its display and camera modules have
steadily increased. Wider data busses operating at higher
frequencies have been implemented between these modules, resulting
in significant increases in power consumption, routing complexity,
sensitivity to EMI radiation and cost. To alleviate these concerns,
QUALCOMM defined the MDDI specification, which consists of a high
speed low power interface carrying video, audio and control packets
to connect the host processor to the display module. QUALCOMM's
chipsets integrate an MDDI host and an MDDI client solution is
required adjacent to the display module to direct the data streams
to the appropriate resources. Today, advanced displays for mobile
handsets feature resolutions of QVGA or greater. To address the
finer pixel pitch requirements of these small, high resolution
displays, manufacturers are adopting new design approaches based
upon low temperature polysilicon (LTPS) and amorphous silicon (aSi)
TFT architectures that allow the display drivers to be deposited
directly on the display's glass substrate, resulting in a reduced
bill of materials. Key Features The CM5100 supports all necessary
video, audio and control packet types recommended by the MDDI
specification. The integrated MDDI client transceiver is Type I
(internal mode, 15 cm maximum cable length), consisting of one data
pair, one strobe pair and a dedicated power supply pair that can
support a data rate of up to 385Mbps. As a result, the CM5100
requires only six lines operating at lower power compared to
traditional parallel interfaces that could include up to sixty
lines to control both displays and other resources. The internal
video mapper contained in the CM5100 enables it to operate as a
display controller with an integrated frame buffer for a main panel
of up to QVGA resolution through a standard RGB interface, and
support a secondary "smart" display through a CPU type of
interface. Audio packets can also be transferred through the MDDI
pipe and be redirected to a local stereo audio codec through the
I2S interface. The I2C host interface allows connecting the CM5100
to any I2C slave device allowing it to be controlled through the
MDDI interface. The CM5100 is developed in a low power process
technology and features extensive power management modes to provide
minimal power consumption. The CM5100, housed in a 100 bump, 0.5mm
pitch Wafer Level Chip Scale Package with a form factor of just
5.0mm x 5.0mm, is the industry's smallest MDDI based display
controller. Pricing and Availability Evaluation boards and chip
samples of the CM5100 are available now. Chip pricing starts at
$6.00 in 1,000 unit quantities. Volume production is scheduled for
Q4 2006. About California Micro Devices Corporation California
