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
