Serial Interface Considerations
7.1 MPU-6500 Supported Interfaces
The MPU-6500 supports I2C communications on both its primary (microprocessor) serial interface and its
auxiliary interface..
The MPU-6500’s I/O logic levels are set to be VDDIO.
The figure below depicts a sample circuit of MPU-6500 with a third party magnetometer attached to the
auxiliary I2C bus. It shows the relevant logic levels and voltage connections.
Note: Actual configuration will depend on the auxiliary sensors used.
Figure 13: I/O Levels and Connections
Note: The Interrupt line should be connected to a pin on the Application Processor (AP) that can bring the AP out of suspend
mode.
