3-axis accelerometers with digital output

21 January 2009 Telecoms, Datacoms, Wireless, IoT

STMicroelectronics has introduced a new family of high-performance three-axis linear accelerometers with digital output. All three devices – LIS331DLH, LIS331DLM and LIS331DLF – integrate a host of smart embedded features, including low-power mode, auto wake-up function, free fall motion and 6D-orientation detection, as well as a standard SPI/I²C digital interface. Based on the needs of a specific application, customers can select a 6-, 8- or 12-bit device, all pin-to-pin, motion and software compatible. The 6D recognition signals if the accelerometer is up or down along all three axes (x,y,z). A configurable high-pass filter can be turned on to enable motion-activated functions and vibration monitoring regardless of whether the end product is tilted or placed upside down at the moment of measurement.
