ST LIS33DE MEMS motion sensor 3-axis - ±2g/±8g smart digital output nano accelerometer handbook

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 interrupts, or to be used in combination with a low-pass filter to generate a 2-bit activity indicator.
