FIS1100 Intelligent MEMS IMU

onsemi's FIS1100 6D IMU with motion co-processor and sensor fusion library reduces processor power consumption by 10 times

Image of Fairchild's FIS1100 Intelligent MEMS IMUonsemi's FIS1100 is the world's first complete consumer 6D MEMS inertial measurement unit (IMU) with sensor fusion to specify system level orientation accuracy. When using the FIS1100 in combination with the supplied XKF3 9D sensor fusion, the system features an accurate ±3° pitch and roll orientation, and a ±5° yaw/heading typical specification. The FIS1100 incorporates a 3-axis gyroscope and a 3-axis accelerometer, and can connect an external 3-axis magnetometer through an I2C master thus forming a complete 9DOF system.

The FIS1100 also incorporates an advanced vector digital signal processor (DSP) motion co-processor called the AttitudeEngine™. The AttitudeEngine efficiently encodes high frequency motion at high internal sampling rates, preserving full accuracy across any output data rate. This enables the application to utilize low output data rates (ODR) or on-demand (host polling) and still acquire accurate 3D motion data. The AttitudeEngine reduces the data processing and interrupt load on a host processor without compromising 3D motion tracking accuracy. The result is very low total system power consumption in combination with high accuracy, essential features for many portable and battery powered applications.

Features
  • World's first complete consumer IMU with sensor fusion library to specify orientation accuracy: ±3° pitch and roll, ±5° yaw/heading 3-axis gyroscope and 3-axis accelerometer in a small 3.3 mm x 3.3 mm x 1 mm LGA package
  • Optimized 9D sensor fusion library (XKF3) featuring in-use auto-calibration enabling accurate 3D orientation (quaternion) and high-pass 3D velocity motion tracking
  • Complete system solution for 3D motion tracking
  • Integrated AttitudeEngine motion co-processor with vector DSP performs sensor fusion at 1 kHz sampling rate, while outputting data to host processor at a lower rate to improve accuracy while reducing processor MIPS, power, and interrupt requirements
