General Description
The BMC150 is an integrated electronic compass solution for consumer market
applications. It comprises a 12bit leading edge triaxial, low-g acceleration sensor and an
ultra-low power, high precision triaxial magnetic field sensor. It allows measurements of
acceleration and magnetic field in three perpendicular axes. Performance and features
of both sensing technologies are carefully tuned and perfectly match the demanding
requirements of all 6-axis mobile applications such as electronic compass, navigation or
augmented reality.
An evaluation circuitry (ASIC) converts the output of the micromechanical sensing
structures (MEMS) to digital results which can be read out over the industry standard
digital interfaces.
Package and interfaces of the BMC150 have been designed to match a multitude of
hardware requirements. As the sensor features an ultra-small footprint and a flat
package, it is ingeniously suited for mobile applications.
The BMC150 offers ultra-low voltage operation (VDD voltage range from 1.62V to 3.6V,
VDDIO voltage range 1.2V to 3.6V) and can be programmed to optimize functionality,
performance and power consumption in customer specific applications. The
programmable interrupt engine sets new standards in terms of flexibility.
The BMC150 senses orientation, tilt, motion, shock, vibration and heading in cell
phones, handhelds, computer peripherals, man-machine interfaces, virtual reality
features and game controllers.
