The new sensor offers a full-scale output range of +/-2.0g and it is suitable for low-frequency vibration monitoring at very low power consumption .It incorporates a power-down mode to reach 1uA supply current and built-in self-test capability that allows the customer to  verify  the functioning  of the sensor after it has been assembled on board.

The LIS302ALK uses ST’s ECOPACK lead-free technology for RoHS-compliance (the EU’s Restriction on Use of Hazardous Substances Directive).

ST’s family of LIS302 MEMS motion sensors delivers flexibility in terms of output signals and sensitivity, addressing different system needs and hardware characteristics in a wide range of low-g applications. Areas of use include free-fall detection for data-integrity protection in hard-disk drives, vibration monitoring and compensation, damage prevention, remote control, as well as motion user interfaces in mobile and gaming devices.

ST’s LIS302 family of motion sensors can also be used to manage power consumption of products that need to be powered on (or off) while or after they have been touched or moved. For example, motion sensors can activate a remote control when someone picks it up, controlling the overall power consumption of the circuitry. In medical applications, the sensors can be used to monitor motion or detect the position/activity level of patients.

The MEMS market is one of the most exciting segments of the semiconductor industry, forecast to grow at around 50% over the next five years, heading towards $10 billion by 2010.*

Samples of ST’s LIS302ALK are available now, with volume production starting in February 2007. Unit pricing is $2.95 for quantities of 30,000 pieces. For further information on the LIS302ALK and ST’s complete MEMS portfolio see www.st.com/mems
