Market's Slimmest Digital Accelerometer From STMicroelectronics Enables Advanced Motion Control in Clam-Shell Phones

Geneva, Switzerland (ots/PRNewswire)

- MEMS-based Sensor Packs World-class Performance, Smart Features,
and  Digital Output Into 1mm-high package
STMicroelectronics (NYSE:STM), a leading supplier of MEMS
(Micro-Electro-Mechanical System) devices, today announced that it
has expanded its portfolio of three-axis accelerometers with the
thinnest digital-output sensor on the market. Embedding high
performance and smart functionality in a 1-mm-high package, ST's
LIS3LV02DL opens new possibilities for advanced motion-based
applications in ever-more popular, thin-profiled clamshell mobile
phones.
MEMS-based accelerometers have enabled the introduction of
high-performance, cost-effective motion-based user interfaces in
mobile applications, including gesture recognition, motion-activated
scrolling, and navigation on the phone display. ST's new ultra-slim
3D sensor with digital output extends these advanced capabilities to
the clamshell form factor, which is expected to account for 41% of
the estimated 750 million handsets sold worldwide in 2006, and
represent the majority of mobile phone sales by 2008.
The LIS3LV02DL is the newest member in ST's market-unique family
of three-axis accelerometers with a standard SPI/I2C digital
interface. The digital output streamlines communication with the
baseband chip; it eliminates the need for a dedicated A/D converter
on each input channel and enables the sensor to share interfaces with
other devices, thereby saving further space in slim-form-factor
systems.
ST's LIS3LV02DL embeds a host of smart features, including a
free-fall and wake-up flag, adjustable bandwidth, and direction
detection.
Adjustable bandwidth provides optimized performance for different
frequencies. The bandwidth can be flexibly changed with a software
command, allowing designers to effectively combine measurements of
slow and fast motions, such as tilt and vibrations, in one
application. When a threshold is crossed along any of the three axes,
the embedded direction detection helps quickly understand in which
direction the sensor is moving before any data calculations are made.
The new sensor can measure both tilt and acceleration along all
three (x, y, z) axes at a very low noise level and minimized power
consumption, which is especially critical in battery-operated
portable systems, such as mobile phones. Other areas of application
include PDAs, MP3 players, laptop PCs, and remote controls for
consumer appliances.
Manufactured in ST's proprietary THELMA15 technology, the
LIS3LV02DL provides both +/-2.0g and +/-6.0g full-scale acceleration
ranges, which can be changed by software command even during
operation. The device offers high temperature stability and tight
offset tolerances and its robust design provides very high immunity
to vibration and a shock resistance up to 10,000g.
Supplied in 16-pin LGA and QFN28 packages, the LIS3LV02DL is
sampling now, with volume production starting in March 2006. Unit
pricing is less than $4 in volume.

About ST's MEMS Portfolio
ST's MEMS inertial sensors target a wide array of applications in
computer peripherals, consumer, telecommunications, and automotive
markets. ST accelerometers initiate the deployment of car alarm
systems and detect excessive vibrations in electronic home
appliances. ST's MEMS devices also open up new possibilities for
intuitive man-machine interaction in gaming and mobile applications,
enabling users to interact with the system by simply tilting the
device in the desired direction. Market analysts predict that by
2010, there will be one accelerometer in each portable
hard-disk-based device (laptops, audio/video players) and every
mobile phone, representing a total amount of more than 1.2 billion
units.
