MPU-9150 Product Specification

Document Number: PS-MPU-9150A-00

Revision: 4.3

Release Date: 9/18/2013

10 Serial Interface Considerations

10.1 MPU-9150 Supported Interfaces

The MPU-9150 supports I2C communications.

10.2 Logic Levels

The MPU-9150’s I/O logic levels are set to be either VDD or VLOGIC, as shown in the table below.

I/O Logic Levels

MICROPROCESSOR LOGIC LEVELS

(Pins: SDA, SCL, AD0, CLKIN, INT)

VLOGIC

AUXILIARY LOGIC LEVELS

(Pins: ES_DA, ES_CL)

VDD

VLOGIC may be set to be equal to VDD or to another voltage. However, VLOGIC must be ≤ VDD at all

times. VLOGIC is the power supply voltage for the microprocessor system bus and VDD is the supply for the

auxiliary I2C bus, as shown in the figure of Section 10.3.
