MPU-6000/MPU-6050 Product Specification
Revision: 3.4 Release Date: 08/19/2013
10 Serial Interface Considerations (MPU-6050) 10.1 MPU-6050 Supported Interfaces
The MPU-6050 supports I2C communications on both its primary (microprocessor) serial interface and its auxiliary interface.
10.2 Logic Levels
The MPU-6050’s I/O logic levels are set to be VLOGIC, as shown in the table below. AUX_VDDIO must be set to 0.
I/O Logic Levels vs. AUX_VDDIO MICROPROCESSOR LOGIC LEVELS AUXILLARY LOGIC LEVELS AUX_VDDIO
(Pins: SDA, SCL, AD0, CLKIN, INT) (Pins: AUX_DA, AUX_CL) 0 VLOGIC VLOGIC Note: The power-on-reset value for AUX_VDDIO is 0. When AUX_VDDIO is set to 0 (its power-on-reset value), VLOGIC is the power supply voltage for both the microprocessor system bus and the auxiliary I2C bus, as shown in the figure of Section 10.3. 38 of 52
