Fairchild brings 'smart' IMUs to MEMS market

All its algorithms are optimised for ARM processors, which it claims dominate the wearables industry. Fairchild also provides two-versions of a complete evaluation and development system, one of which requires an Arduino board for its application processor, and the other of which comes complete with an NXP application processor board onto which the Fairchild Arduino-compatible board plugs. The Fairchild FIS1100 sensor board also holds an AKM three-axis magnetometer to complete the nine-axis sensor fusion.

Fairchild's low-frequency connection to the application processor (1Hz to 64Hz) is just as accurate as a result of local processing of raw data in its AttitudeEngine, as much higher speeds (1kHz) that burdens the application processor.
