General description
FXOS8700CQ is a small, low-power, 3-axis, linear accelerometer and 3-axis, magnetometer combined into a single package. The device features a selectable I2C or point-to-point SPI serial interface with 14-bit accelerometer and 16-bit magnetometer ADC resolution along with smart-embedded functions. FXOS8700CQ has dynamically selectable acceleration full-scale ranges of ±2 g/±4 g/±8 g and a fixed magnetic measurement range of ±1200 μT. Output data rates (ODR) from 1.563 Hz to 800 Hz are selectable by the user for each sensor. Interleaved magnetic and acceleration data is available at ODR rates of up to 400 Hz. FXOS8700CQ is available in a plastic QFN package and it is guaranteed to operate over the extended temperature range of –40 °C to +85 °C.

APPLICATIONs
◾ Security: motion detection, door opening, smart home applications, robotics, and unmanned aerial vehicles (UAVs) with electronic compass (e-compass) function.
◾ Medical applications: patient monitoring, fall detection, and rehabilitation
◾ E-compass in mobile devices, tablets, and personal navigation devices
◾ User interface (menu scrolling by orientation change, tap detection for button replacement)
◾ Orientation detection (portrait/landscape: up/down, left/right, back/front orientation identification)
◾ Augmented reality (AR), gaming, and real-time activity analysis (pedometry, freefall, and drop detection for hard disk drives and other devices)
◾ Power management for mobile devices using inertial and magnetic event detection
◾ Wearable devices: motion detection, activity monitoring, sports monitoring, context awareness, and shock and vibration monitoring (mechatronic compensation, shipping, and warranty usage logging)
