Description

The LIS331DL, belonging to the “nano” family of

ST motion sensors, is the smallest consumer low-

power three axes linear accelerometer. The

device features digital I2C/SPI serial interface

standard output and smart embedded functions.

The sensing element, capable of detecting the

acceleration, is manufactured using a dedicated

process developed by ST to produce inertial

sensors and actuators in silicon.

The IC interface is manufactured using a CMOS

process that allows to design a dedicated circuit

which is trimmed to better match the sensing

element characteristics.

The LIS331DL has dynamically user selectable

full scales of

±2g/±8g and it is capable of

measuring accelerations with an output data rate

of 100 Hz or 400 Hz.

A self-test capability allows the user to check the

functioning of the sensor in the final application.

The device may be configured to generate inertial

wake-up/free-fall interrupt signals when a

programmable acceleration threshold is crossed

at least in one of the three axes. Thresholds and

timing of interrupt generators are programmable

by the end user on the fly.

The LIS331DL is available in plastic Land Grid

Array package (LGA) and it is guaranteed to

operate over an extended temperature range from

-40 °C to +85 °C.
