The LIS3DE is an ultra-low-power high-performance 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 order to limit intervention by the host processor. The LIS3DE is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

lis3de是一個超低功耗高性能的三軸線性加速度計屬于“納米”家庭，數字I2C/SPI串行接口標準輸出。該設備具有超低功耗運行模式，讓先進的省電和智能嵌入式功能。
