STMicroelectronics (NYSE: STM),
a global leader in developing and delivering semiconductor solutions across
the spectrum of microelectronics applications, 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.
