Description
The LIS202DL is an ultra compact low-power two
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 LIS202DL 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 interrupt signals when a programmable
acceleration threshold is crossed at least in one of
the two axes. Thresholds and timing of interrupt
generators are programmable by the end user on
the fly.
The LIS202DL 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 LIS202DL belongs to a family of products
suitable for a variety of applications:
– Motion activated functions
– Gaming and Virtual Reality input
devices
– Vibration Monitoring and Compensation
