6-Axis Xtrinsic Sensor with Integrated Linear Accelerometer and Magnetometer

FXOS8700CQ is a small, low-power 6-axis linear accelerometer and magnetometer combined into a single package. The device features a selectable digital I2C or SPI serial interface with 14-bit accelerometer and 16-bit magnetometer resolution along with smart-embedded functions. FXOS8700CQ has dynamically selectable acceleration full scales of ±2g/±4g/±8g 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.

FEATUREs
• 1.95V to 3.6V VDD supply voltage, 1.62V to 3.6 VDDIO voltage
• ±2g/±4g/±8g dynamically selectable acceleration full-scale range
• ±1200 µT magnetic sensor full-scale range
• Output Data Rates (ODR) from 1.563 Hz to 800 Hz for each sensor, and up to 400 Hz when operated in hybrid mode with both sensors active
• Low noise: < 150 μg/√Hz acceleration, < 1 μT rms magnetic
• 14-bit resolution for acceleration measurements
• 16-bit resolution for magnetic measurements
• Footprint compatible with Xtrinsic MMA8451, 2, 3
• Embedded programmable acceleration event functions:
   — Freefall and Motion Detection
