BMC156
型号: BMC156
产品详情

GENERAL DESCRIPTIONHoused in an LGA package with a footprint of merely2.2 x 2.2 mm² and 0.95 mm height, BMC156 is an extremelysmall low power and low noise 6-axis digital compass. Due toits pin-compatible pin-out it fits well on a 2 x 2 standard accelerometer landing pattern (BMA). It measures the earth’s geomagnetic field as well as dynamic and static acceleration in allthree dimensions and outputs tilt-compensated heading andorientation information. The integrated accelerometer providesthe functionalities of Bosch Sensortec’s leading-edge 12 bitdigital accelerometer, including a 32 frame FIFO buffer storingacceleration data. Due to its small package size and itsadvanced power management, BMC156 is ideally suited forvirtual reality and navigation applications or motion tracking inhandhelds like mobile phones, tablet PCs, notebooks, portablemedia players, man-machine interfaces and game controllers.With an increased magnetic measurement range, BMC156offers high PCB placement flexibility to the developer ofhandheld devices.SENSOR FEATURESThe eCompass comprises a 3-axis geomagnetic sensor basedon Bosch’s proprietary FlipCoreTM technology and a 3-axis 12bit accelerometer. The accelerometer provides the deviceorientation for tilt compensated heading output. At the same timeit features the functions of a state-of-the art standalone accelerometer and can be operated independently.TECHNICAL SPECIFICATIONSBMC156 Technical dataDigital interfaces I2C, SPI (3/4 wire) interrupt pinCurrent consumption– regular mode– low-power mode540 µA @ 10 Hz190 µA @ 10 HzSupply voltage 1.62 … 3.6 VSupply voltage I/O 1.20 … 3.6 VOperatingtemperature-40 … +85 °CLGA package 2.2 x 2.2 x 0.95 mm3Geomagnetic sensorMeasurement range ± 1300 µT (x-,y-axis)± 2500 µT (z-axis)Resolution 0.3 µTAcceleration sensorStand-alone operation supportedResolution 12 bitProgrammableg-range±2 g; ±4 g; ±8 g; ±16 gZero-g offset (typ.) ±80 mgSensitivity tolerance ±4 %Interrupt engineAccelerometerinterruptsOrientation/flat detection,any motion, tap/double tap,sensing, low-/high-g threshold,slow motion/no motion detection,data readyMagnetometerinterruptsmagnetic data ready,magnetic threshold detectionFIFO data bufferaccelerometer 32 sample depth for each axis
