The FXLS8471Q Xtrinsic accelerometer is highly versatile for industrial and consumer high-performance low-g applications that offer noise density, board mount offset, temperature performance and sensitivity. Integrated motion detection features include tilt, shake and tap detection with a new vector magnitude output that simplifies implementation and reduces power consumption. This new FXLS8471Q accelerometer has a SPI interface that is pin-compatible with Freescale’s industry-leading I2C accelerometer portfolio.
