On-chip temperature sensor It can measure magnetic fields within the full scale Selftest signal available range of 30 Gauss (G), with up to 0.0625mG per LSB Data ready Interrupt (I3C only) resolution at 20bits operation mode and 2mG total RMS Low power consumption noise level, enabling heading accuracy of 1 in 1 A power down current electronic compass applications. Contact MEMSIC for 2 I C slave, FAST ( 400 KHz) mode access to advanced calibration and tilt-compensation I3C interface, Compatible with MIPI I3C algorithms. specfication version 1.0 An integrated SET/RESET function provides for the 1.62V to 3.6V wide range single power supply 2 elimination of error due to Null Field output change with 1.2V compatible I C interface temperature. In addition, it clears the sensors of any 1.8V compatible I3C interface residual magnetic polarization resulting from exposure RoHS compliant to strong external magnets. The SET/RESET function can be performed for each measurement or periodically as the specific application requires. APPLICATIONS The MMC5633NJL is in wafer level package with an Electronic Compass & GPS Navigation ultra-small size of 0.85 x 0.85 x 0.4 mm and with an Position Sensing operating temperature range from -40 C to +85 C.

External magnetic field on each axis not continuously higher than 30G. 2. Supply current is proportional to how many measurements performed per second, 75Hz (maximum) for BW=00. 3. Based on 3lots characterization result. 4. The 1000 Hz ODR is available by writing 255 into Register ODR and setting hpower to 1. 5. MEMSIC product enables users to utilize heading accuracy to be 1.0 degree typical when using MEMSICs proprietary software or algorithm. 6. Sensitivity of the orthogonal axes is analytically derived from raw data and is subsequently processed by MEMSIC software drivers. 7. This is the magnitude of external field that can be tolerated without changing the sensor characteristics. If the disturbing field is exceeded, a SET/RESET operation is required to restore proper sensor operation. 8. Based on shipment test result.
