LIS2DETR

加速度计, MEMS, 3轴, 数字, X, Y, Z, ± 2g, ± 4g, ± 8g, ± 16g, 1.71 V, 3.6 V, LGA

The LIS2DE is an ultra-low-power high-performance 3-axis linear accelerometer belonging to the “femto” 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 LIS2DE 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 LIS2DE 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 LIS2DE 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.
