MEMS eCompass -- 3 axis accelerometer + 3 axis magnetometer

ST Hawks Smallest MEMS Compass
2 Aug 2013

PORTLAND, Ore. -- ST Microelectronics has introduced what it is calling
the world's smallest digital e-compass -- a three-axis magnetometer
combined with a three-axis accelerometer on a 2x2mm MEMS chip.

By saving board space on next-generation mobile devices, this device
should enable new ultra-miniature, location-aware applications.
Micro-electromechanical systems already provide much of the smarts to
smartphones, and ST is already a major supplier for devices from Apple's
iPhone to Samsung's Galaxy. However, a new generation of smartphones and
other personal devices will have even less board space.
