FXLS8964AFR3

FXLS8964AFR3 is a compact 3-axis MEMS accelerometer designed for use in automotive remote keyless entry (key fob) applications that require ultra-low-power wake-up on motion. The part supports both high-performance and low-power operating modes, allowing maximum flexibility to meet the resolution and power needs for various use case implementations. A number of advanced, integrated digital features enable designers to reduce the overall system power consumption and simplify host data collection. The combination of sensor performance, system power-saving features, and extended over-temperature-range performance makes FXLS8964AF an ideal accelerometer for automotive security and convenience applications.
