Freescale Xtrinsic eCompass Software Provides Fast, Accurate Orientation Data for Mobile Devices

New sensor fusion solution delivers highly accurate context awareness for mobile, 3D gaming, and eHealth applications

BARCELONA, Spain--(BUSINESS WIRE)--Feb. 28, 2012-- Smart devices in a variety of markets require precise heading information from multiple sensors to better understand the context of their surroundings. Freescale Semiconductor (NYSE: FSL) today announced Xtrinsic eCompass software, a new sensor fusion solution that works together with a Freescale Xtrinsic accelerometer and magnetometer to provide highly accurate magnetic data. With Xtrinsic eCompass software, mobile applications such as augmented reality, 3D gaming, eHealth and location-based services have faster and more accurate orientation data with optimized performance to significantly enhance the user experience.

“As multiple sensors are added to smartphones and other mobile devices, more sophisticated software is required to realize the system performance benefits of a multi-axis sensor system,” said Seyed Paransun, vice president and general manager of Freescale’s Sensor & Actuator Solutions Division. “Our new Xtrinsic eCompass software is just one example of providing Xtrinsic sensor solutions supported and differentiated by performance oriented software algorithms for quick implementation and time to market.”

According to an IHS iSuppli MEMS & Sensors H2 2011 Special Report, the compound annual growth rate (CAGR) of magnetic sensors is 14 percent in the wireless market and 56 percent in the consumer market, while global revenue from motion sensor technology in smartphones and tablets is expected to nearly double over the next five years, expanding from $1.1 billion in 2011 to $1.9 billion by 2015. Mobile applications rely on compass readings based on combined data extracted from magnetometers and accelerometers, and Xtrinsic eCompass calibration and compensation software is necessary to correct for magnetic distortions prevalent in today’s complex devices.

Advanced sensor fusion algorithms allow the inherent strengths of various sensors to trade off one another in order to achieve far greater optimization. Using Freescale’s Xtrinsic eCompass software, designers can quickly solve their design challenges and employ highly accurate sensing technologies for a variety of mobile applications. Supporting application note documentation, development tools and an embedded simulation framework are just a few of the essential tools provided to make this software integration effort seamless.

Xtrinsic eCompass software: product features

The combination of Freescale’s Xtrinsic accelerometers and Xtrinsic MAG3110 magnetometer with Xtrinsic eCompass software enables full tilt-compensated and calibrated electronic compass data. Available in source code for exclusive use with Freescale’s Xtrinsic smart sensing solutions and compatible with existing mobile operating systems and hardware, Xtrinsic eCompass software is easily integrated with a full range of mobile solutions.

Freescale’s Xtrinsic eCompass software features include:

  • Xtrinsic eCompass with tilt-compensation
  • Roll, pitch and compass angles
  • 4 parameter hard iron only option
  • 7 parameter hard iron with soft iron gain calibration
  • 10 parameter hard iron with full off axis soft iron calibration
  • Standard ANSI C source code
  • 20 KB compiled code size
  • 6.5 KB RAM requirement
  • Sensor simulation module included for immediate verification

Availability and pricing

Xtrinsic eCompass software is available online through a click-through software license at

  • The four-element model supports hard iron interference correction and is available free of charge for evaluation and for commercial use if used with the Xtrinsic MAG3110. This is recommended for customers with minimal soft iron distortion and limitation to processor RAM.
  • The seven-element model supports both hard iron and soft iron interference correction and is available free of charge if used with the Xtrinsic MAG3110. This is recommended for customers with typical soft iron interference.
  • The ten-element model and customer solutions will continue to be supported through manual license agreements

Freescale’s Sensor Toolbox is a common platform for accelerometers, magnetometers, pressure and touch sensors. The development board for use in electronic compass development is:

  • Xtrinsic MAG3110 magnetometer RD4247MAG3110 development board with the USB board for a suggested resale price of $99 (USD). For more magnetometer training, videos and technical documentation, visit
