Product Introduction
FXOS8700CQ is a small, low- power, 3- axis, linear accelerometer and 3- axis, magnetometer combined into a single package. The device features a selectable 1°C 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 ± 2g / ± 4g / ± 8g and a fixed magnetic measurement range of ± 1200μT. Output data rates (ODR) from 1.563Hz to 800Hz are selectable by the user for each sensor. Interleaved magnetic and acceleration data is available at ODR rates of up to 400Hz. 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
- Complete 6-axis, e-compass hardware solution
- 1.95V to 3.6V VDD supply voltage, 1.62V to 3.6V VDDIO voltage
- ± 2g / ± 4g / ± 8g dynamically selectable acceleration full-scale range
- ± 1200μT magnetic sensor full-scale range
- Output data rates (ODR) from 1.563Hz to 800Hz for each sensor, and up to 400Hz when operated in hybrid mode with both sensors active
- Low noise: < 126μg / √Hz acceleration noise density at 200Hz bandwidth, < 100nT / √Hz magnetic noise density at 100Hz bandwidth
- 14-bit ADC resolution for acceleration measurements
- 16-bit ADC resolution for magnetic measurements
- Low power: 240μA current consumption at 100Hz, and 80μA at 25Hz with both sensors active
- Embedded programmable acceleration event functions
- Freefall and motion detection
- Transient detection
- Vector- magnitude change detection
- Pulse and tap detection (single and double)
- Orientation detection (portrait/landscape)
- Embedded programmable magnetic event functions
- Threshold detection
- Vector- magnitude change detection
- Autonomous magnetic min/max detection
- Autonomous hard- iron calibration
- Programmable automatic ODR change using auto- wake and return- to- sleep functions to save power. This function works with both magnetic and acceleration event interrupt sources.
- 32- sample FIFO for acceleration data only.
- Integrated accelerometer self- test function
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)
