World's Thinnest MEMS Accelerometer from STMicroelectronics Drives
Movement-Activated features into Ultra-Slim Designs

Low-profile high-stability motion-sensing IC allows mobile applications to
deliver enhanced user experiences

GENEVA, June 10 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM), the
world leader in MEMS (Micro Electro-Mechanical Systems) devices for consumer
and portable applications(1), has introduced the world's thinnest three-axis
digital MEMS accelerometer. The LIS302DLH is a high-performance high-stability
16-bit device that is only 0.75mm high and shares the 3 x 5mm footprint of
other devices in ST's Piccolo MEMS family for use in ultra-space-saving
product designs.

Micro-mechanical components are built on a single chip using well established
and robust processes similar to those for conventional semiconductor
fabrication. So accelerometers and other devices such as gyroscopes can be
produced within extremely small dimensions, and also benefit from low
friction, low wear, and high shock resistance. Hundreds of millions of MEMS
components are already in service, supporting adaptive and interactive
features in consumer products such as smart-phone handsets, GPS devices,
portable computers, game controllers, automotive subsystems, and industrial,
medical, and scientific equipment.

Applications for ST's LIS302DLH digital three-axis accelerometers include
motion sensing, orientation awareness, free-fall detection, and vibration
monitoring. Low-voltage operation and low power consumption make this device
ideal for battery-powered products. It has a power-saving shutdown mode, and
wakes automatically when motion is detected. The integrated digital circuitry
outputs acceleration measurements up to +/-8g in the industry-standard I2C/SPI
serial format, allowing direct connection to the system processor with no
external components required. The LIS302DLH is also pin-to-pin compatible with
other 3-axis devices in ST's Piccolo digital family, including the LIS302DL
and LIS35DE, providing the market with a high level of product scalability.

Samples are available immediately, and mass production is scheduled for early
Q3 2009 at $1.35 for orders over 10,000 pieces.
