Description

The AIS2DW12 is an ultra-low-power three-axis

linear accelerometer which leverages on the

robust and mature manufacturing processes

already used for the production of micromachined

accelerometers and designed to address nonsafety

automotive applications.

The AIS2DW12 has four different ultra-low-power

modes, two user-selectable full scales (?2g/?4g)

and is capable of measuring accelerations with

output data rates from 1.6 Hz to 100 Hz.

The AIS2DW12 has an integrated 32-level first-in,

first-out (FIFO) buffer allowing the user to store

data in order to limit intervention by the host

processor.

The embedded self-test capability allows the user

to check the functioning of the sensor in the final

application.

The AIS2DW12 has a dedicated internal engine

to process motion and acceleration detection

including free-fall, motion and no-motion, wakeup,

activity/inactivity and 6D/4D orientation.

The AIS2DW12 is available in a small thin plastic

land grid array package (LGA) and it is

guaranteed to operate over an extended

temperature range from -40 °C to +85 °C.

Applications

? Car key applications

? Inclination / orientation detection

? Motion-activated functions

? Gesture recognition

? Free-fall detection

? Smart power saving
