NOTE1: Rp are typically 4.7k⦠pullup resistors to VDD/VDDIO, per I2C specification. When
pin VDD/VDDIO is powered down, SDA and SCL will be driven low by internal ESD diodes.
NOTE2: Attach typical 4.7k⦠pullup resistor if INTN is defined as open-drain.
NOTE3: Bold pin names are from MC6470 and MC7030. Connection to VDDM is required, INTM
and A5 are optional.
Figure 6. Typical Application Circuit for 3DOF, 6DOF, 9DOF Pin Compatibility (MC6470 and MC7030)
In typical applications, the interface power supply may contain significant noise from external
sources and other circuits which should be kept away from the sensor. Therefore, for some
applications a lower-noise power supply might be desirable to power the VDD/VDDIO pin.
