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是一个超低功耗高性能的三轴线性加速度计属于“纳米”家庭，数字I2C/SPI串行接口标准输出。该设备具有超低功耗运行模式，让先进的省电和智能嵌入式功能。

lis3de动态用户可选的全尺度的±2g／±4G /±8g /±16G和能够测量加速度的输出数据速率从1赫兹到5千赫。自检功能允许用户检查传感器在最终应用程序的功能。该装置可用于产生由两个独立的惯性唤醒/自由落体事件以及设备本身的位置中断信号。阈值和中断发生器的时间是可编程的终端用户的飞行。的lis3de集成了一个32级的先入先出（FIFO）缓冲器允许用户以限制存储数据的主机处理器干预。在一个小的lis3de薄塑料栅格阵列（LGA）封装，可它是保证工作在扩展的温度范围从- 40°C + 85°C.
