LIS331DLM: ±2 g /±4 g /±8 g digital output

high performance ultra low-power 3-axis accelerometer

Introduction

This document provides application information for the low-voltage 3-axis digital output

linear MEMS accelerometer housed in an LGA package.

The LIS331DLM is a high performance ultra low-power 3-axis linear accelerometer which

standard output.

The device features ultra low-power operational modes that allow advanced power saving

and smart sleep to wake functions.

capable of measuring acceleration with output data rates from 0.5 Hz to 400 Hz.

The self-test capability allows the user to check the functioning of the sensor in the final

application.

The device can be configured to generate interrupt signals in response to inertial

wakeup/free-fall events or based on the position of the device itself.

The thresholds and timing of interrupt generators are programmable by the end user “on the

fly”. The LIS331DLM is available in a small, thin plastic land grid array (LGA) package and is

guaranteed to operate over an wide temperature range of -40 °C to +85 °C.
