The LIS33DE is an ultra compact low-power three axis linear accelerometer belonging to the "nano" family of ST motion sensors. 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 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 LIS33DE 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 axis. Thresholds and timing of interrupt generator are programmable by the end user on the fly.

The LIS33DE is available in plastic Thin Land Grid Array package (LGA) and it is designed to operate over an extended temperature range from -40°C to +85°C.
