BMC156

COMPASS WITH 3-AXIS GEOMAGNETIC SENSOR

AND

12 BIT 3-AXIS ACCELEROMETER

Key features

Three-axis magnetic field sensor and 12bit three-axis accelerometer in one package

 Accelerometer can still be used independently from magnetometer operation

 Ultra-Small package

12-Pin LGA package, footprint 2.2 × 2.2mm2,

height 0.95 mm

 Digital interface

SPI (4-wire, 3-wire), I²C, 2 interrupt pins

(1 acceleration sensor, 1 magnetic sensor interrupt pin)

 Low voltage operation

VDD supply voltage range: 1.62V to 3.6V

VDDIO interface voltage range: 1.2V to 3.6V

 Flexible functionality

Acceleration ranges ±2g/±4g/±8g/±16g

Acceleration Low-pass filter bandwidths 1 kHz - <8Hz

 Magnetic field range

±1300µT (x, y-axis), ±2500µT (z-axis)

Magnetic field resolution of ~0.3µT

 On-chip FIFO

Integrated FIFO with a depth of 32 frames

 On-chip interrupt controller

Motion-triggered interrupt-signal generation for

- new data (separate for accelerometer and magnetometer)

- any-motion (slope) detection

- tap sensing (single tap / double tap)

- orientation recognition

- flat detection

- low-g/high-g detection

 Ultra-low power

Low current consumption (190µA @ 10 Hz including

accelerometer and magnetic sensor in low power preset),

short wake-up time, advanced features for system power

management

 Temperature range

-40 °C … +85 °C

 Temperature sensor

 RoHS compliant, halogen-free

Typical applications

 Tilt-compensated electronic compass for map rotation, navigation and augmented reality

 6-axis orientation for gaming

 Display profile switching

 Menu scrolling, tap / double tap sensing

 Pedometer / step counting

 Free-fall detection

 Drop detection for warranty logging

 Advanced system power management for mobile applications

 Gaming
