Description

The LIS2DW is an ultra-low-power, high

performance three-axis linear accelerometer

belonging to the “femto” family which leverages

on the robust and mature manufacturing

processes already used for the production of

micromachined accelerometers.

The LIS2DW has user-selectable full scales of

2g/4g/8g/16g and is capable of measuring

accelerations with output data rates from 1.6 Hz

to 1600 Hz.

The LIS2DW 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 LIS2DW has a dedicated internal engine to

process motion and acceleration detection

including free-fall, wakeup, highly configurable

single/double-tap recognition, activity/inactivity,

stationary/motion detection, portrait/landscape

detection and 6D/4D orientation.

The LIS2DW 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

 Motion detection for wearables

 Gesture recognition and gaming

 Motion-activated functions and user interfaces

 Display orientation

 Tap/double-tap recognition

 Free-fall detection

 Smart power saving for handheld devices

 Hearing aids

 Portable healthcare devices

 Wireless sensor nodes

 Motion-enabled metering devices
