GENERAL DESCRIPTIONThe MC6450 is a 6-axis electronic compassthat consists of a 3-axis linear accelerometerand a 3-axis magnetic field sensor, both with anI2C digital interface, in a single package.By combining a high precision magnetic sensorwith a low noise single-chip MEMSaccelerometer, the MC6450 enables industryleading tilt-compensated compass directionalaccuracy.The MC6450 feature set is optimized for cellphones, portable navigation devices and fitnessproducts. Applications taking advantage of highprecision directional pointing include maporientation, virtual reality data overlay,enhanced navigation with dead reckoningassistance and gyroscope replacement.Additionally, the MC6450 maintains standardaccelerometer features such as motion enableduser interface, gesture recognition and gamingcontrol.The MC6450 supplied with mCube eMotion™software eases integration of compassfunctionality into the end product. eMotionsoftware features includes tilt-compensatedheading calculation, hard- and soft-ironcalibration and World Magnetic Model (WMM)compensation.The MC6450 has a linear acceleration full-scalerange of ±8g and low noise magnetic sensorswith up to 0.15µT magnetic field resolution. Asingle I2C interface is available to separatelycontrol magnetometer and accelerometerfunctions, enabling independent operation offunctions for applications flexibility.FEATURES Single-package high performanceeCompasso 3-axis magnetometer and 3-axisaccelerometero Single I2C interface to 400 kHz Magnetometero High performance magneticsensor with 0.15µT resolutiono 0.35uT Noiseo 15-bit resolutiono Broad field range up to ±2.4mTo Programmable output data ratefrom 0.5 to 100 Hz Accelerometero ±8g full-scale acceleration rangeo 14-bit resolution 3 × 3 × 0.95 mm 16-pin LGA package
