Contact MEMSIC for access to On-chip temperature sensor advanced calibration and tilt-compensation algorithms. Motion Detection and Data Ready Interrupt An integrated SET/RESET function provides for the Low power consumption elimination of error due to Null Field output change 1 A power down current with temperature. In addition it clears the sensors of 2 I C Slave, FAST ( 400 KHz) mode any residual magnetic polarization resulting from 1.8V single low power supply compatible exposure to strong external magnets. The 2 Low to 1.2V I C interface SET/RESET function can be performed for each measurement or periodically as the specific RoHS compliant P2P compatible with AK09911 application requires. The MMC3630KJ is packaged in an ultra-small low APPLICATIONS profile BGA package (1.2x 1.2 x 0.5 mm) and with an Electronic Compass & GPS Navigation operating temperature range from -40 C to +85 C. 2 Position Sensing The MMC3630KJ provides an I C digital output with 400 KHz, fast mode operation. DESCRIPTION The MMC3630KJ is a complete 3-axis magnetic sensor with on-chip signal processing and integrated 2 I C bus. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources.
