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
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 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 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
