    ICM-30630 sensor built-in MCU/DMP. Topics covered in this app note include how to use the ICM-30630 in smart motion detection devices, such as smart phones, tablets, wearable activity monitors, and gaming machines, as well as potential design challenges for such applications, including InvenSense’s system reference design called the ICM-30630 SDK (Software Development Kit).

  • Page 6: Sensor Hub Application Systems

    The ICM-30630 serves as an intelligent sensor hub that allows the data collection and processing of such data from internal and external sensors. The multi-cores of ICM-30630 are designed to offload computing and processing tasks from the AP, thereby saving system power and streamlining the overall performance.

    3.6V.  A VDDIO digital supply to make the ICM-30630 digital interface compatible with the AP, wireless transceiver, and external sensors I/O levels. VDDIO allows for a range of 1.71 V to 3.6 V to be applied. The VDDIO voltage must be the same as the host AP, wireless transceiver, and external sensor I/O levels.

  • Page 9: Clock Generation Unit And External Clock Source

    An external digital level clock input from a 32.768 kHz source often found on PMICs and other platform devices can be connected to XTALI pin. We recommend this methodology as it allows ICM-30630 to be synchronized with other devices (i.e. the host) who are also using the same reference clock.

    The ICM-30630 always operates as a slave device when communicating with the AP (master). The slave address of the ICM-30630 is 7 bits long with the LSB (X) determining the final address. The LSB bit of the 7-bit address is determined by the logic level on Pin AD0 (GND or VDDIO). The slave address is 0x6A (Pin AD0 is logic low) and 0x6B (Pin AD0 is logic high).

  • Page 13: Gpio Lines

    ICM-30630 GPIO LINES The ICM-30630 supports three bidirectional GPIO lines that can be configured as general purpose I/O, interrupt input, or interrupt output. All GPIO voltage levels are referenced to VDDIO. We recommend the following GPIO usage assignment: Use ICM-30630 GPIO0 as output to wakeup host MCU. Connect the GPIO0 to host MCU wake-up interrupt input.

    EXTERNAL CRYSTAL Keep any PCB traces between the crystal and the ICM-30630 (Pins 16 and 17), as short as possible. Although currents running through the crystal oscillator are very small, any long lines will make it more sensitive to EMI, ESD and crosstalk.
