ON Semiconductor'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.
