Description

The LIS331DL is the smallest consumer low-

power three axes linear accelerometer with digital

output and smart embedded features. It includes

a sensing element and an IC interface able to

provide the measured acceleration to the external

world through I2C/SPI serial interface.

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 100Hz or 400Hz.

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.
