LIS331DLM MEMS motion sensor: Ultra low power 8bit 3-axis digital accelerometer

The LIS331DLM is an ultra low-power high performance three axes linear accelerometer belonging to the "nano" family, with digital I²C/SPI serial interface standard output.

The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions.

The LIS331DLM has dynamically user selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations 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 may be configured to generate interrupt signal by inertial wake-up/free-fall events as well as by the position of the device itself.

Thresholds and timing of interrupt generators are programmable by the end user on the fly.

The LIS331DLM is available in 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
