Description
The LIS3DE is an ultra-low-power highperformance 3-axis linear accelerometer belonging to the “nano” family, with digital I2C/SPI serial interface standard output. The device features ultra-low-power operational modes that allow advanced power saving and smart embedded functions. The LIS3DE has dynamically user-selectable full scales of 2g/4g/8g/16g and is capable of measuring accelerations with output data rates from 1 Hz to 5 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate interrupt signals by two independent inertial wakeup/free-fall events as well as by the position of the device itself. Thresholds and the timing of interrupt generators are programmable by the end user on the fly. The LIS3DE has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in
