Fairchild enters MEMS market with 6-axis IMU
The IMU can be connected to a tri-axis magnetometer via an I2C bus and when used with the XKF3 software can measure +/-3 degree pitch and roll and +/-5 degree yaw/heading typical specification, Fairchild said.
The main claim for the IMU is that it is lower power than some rival architectures that require high sampling inertial measurement sampling frequencies fed to the host microcontroller. The AttitudeEngine DSP allows sampling to be reduced in frequency and sends processed information to the host MCU less often, Fairchild argues.
The sensor fusion software also performs background calibration that is required for accuracy, consistency, and fluidity.
When Fairchild announced it would be entering the MEMS market in 2014 it said it would do so using foundry manufacturing. However, Fairchild said the FIS1100 is based on a proprietary MEMS process that includes a 60-micron device layer and provides through-silicon via (TSV) interconnects as well as a single-die gyro and accelerometer with a dual-vacuum design.
Fairchild did not disclose where the process has been transferred to for manufacturing.
"The advanced algorithms and deep applications knowhow from the Xsens acquisition position us well in enabling our customers to develop advanced motion solutions in diverse, quickly growing segments within markets such as consumer, industrial, and health," said Mark Thompson, Fairchild CEO, in a statement.
FIS1100 comes in a package measuring 3.3mm by 3.3mm by 1mm and is available for sampling and order placement. The company did not indicate a price for the part.
