10 Serial Interface Considerations (MPU-6050)
10.1 MPU-6050 Supported Interfaces
The MPU-6050 supports I
2
C 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
AUX_VDDIO
MICROPROCESSOR LOGIC LEVELS
(Pins: SDA, SCL, AD0, CLKIN, INT)
AUXILLARY LOGIC LEVELS
(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 I
2
C bus, as shown in the figure of Section 10.3.
