LIS302DL

MEMS motion sensor

3-axis - ±2g/±8g smart digital output “piccolo” accelerometer

Feature

(see Section 8)

Description

The LIS302DL is an ultra compact low-power

three axes linear accelerometer. It includes a

sensing element and an IC interface able to

provide the measured acceleration to the external

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 LIS302DL 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 completely

programmable by the end user on the fly.

The LIS302DL is available in plastic Thin Land

Grid Array package (TLGA) and it is guaranteed

to operate over an extended temperature range

from -40°C to +85°C.

The LIS302DL belongs to a family of products

suitable for a variety of applications:

–

Free-Fall detection

–

Motion activated functions

–

Gaming and Virtual Reality input

devices

–

Vibration Monitoring and Compensation
