STMicroelectronics has introduced a family of three-axis linear accelerometers with digital output. The 3x3x1mm MEMS accelerometers target a wide range of low-g applications, including motion user interfaces or pedometers in mobile phones, gaming devices, remote controllers or portable media players. All three devices - the LIS331DLH, LIS331DLM and LIS331DLF - integrate 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. The new three-part sensor family ensures complete resolution scalability. 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 - so they can be re-used across different projects without the need to change the board and sensor software drivers. The 6D recognition signals if the accelerometer is up or down along all three axes (x, y, z). The devices can be programmed to work in the sleep-to-wake mode, which means that the device keeps the read chain active, consuming less than 10µA and automatically waking up when an event occurs. 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.
