MPU-6000 and MPU-6050 Product Specification Revision 1.0

MPU-6000/MPU-6050 Product SpecificationDocument Number: PS-MPU-6000A-00Revision: 1.0Release Date: 11/24/201011.4 Logic Levels Diagram for AUX_VDDIO = 1The figure below depicts a sample circuit with a third party magnetometer attached to the auxiliary I 2 C bus. Itshows logic levels and voltage connections for AUX_VDDIO = 1. This configuration is useful when theauxiliary sensor has only one supply for logic and power. Note: Actual configuration will depend on theauxiliary sensors used.VLOGICVDD(0V - VLOGIC)VLOGICVLOGICSYSTEM BUSVDD_IOSystemProcessorIOVDDINT(0V - VLOGIC)VDD_IO(0V - VLOGIC)(0V - VLOGIC)CLKINFSYNCSDASCL(0V - VLOGIC)(0V - VLOGIC)I 2 CMaster IOVDDVLOGICVLOGIC(0V, VLOGIC)MPU-6050VLOGICAUX_DAAD0 AUX_CL0V - VDD0V - VDDSDASCLVDDINT 1INT 23 rd ADDRPartyMagnetometer(0V - VLOGIC)0V - VDD(0V - VLOGIC)Voltage/ConfigurationConfiguration 1 Configuration 2VLOGICVDD1.8V±5%2.5V±5%3.0V±5%3.0V±5%AUX_VDDIO 1 1I/O Levels and Connections for Two Example Power Configurations (AUX_VDDIO = 1)Notes:1. AUX_VDDIO determines the IO voltage levels of AUX_DA and AUX_CL. AUX_VDDIO = 1 setsoutput levels relative to VDD.2. Other MPU-6050 logic IO is always referenced to VLOGIC.3. Third-party auxiliary device logic levels are referenced to VDD. Setting INT1 and INT2 to open drainconfiguration provides voltage compatibility when VDD ≠ VLOGIC. When VDD = VLOGIC, INT1 andINT2 may be set to push-pull outputs, and external pull-up resistors are not needed.CONFIDENTIAL & PROPRIETARY 39 of 53
