I2C: INTER-INTEGRATED CIRCUIT INTERFACE

The IGEP

TM

SMARC iMX6 module can be connected to other peripheral devices by four I2C serial buses. There

are eight pins in the SMARC-314 that may be used for this application: I2C_CAM_DAT, I2C_CAM_CK,
I2C_GP_DAT, I2C_GP_CK, I2C_LCD_DAT, I2C_LCD_CK, I2C_PM_DAT and I2C_PM_CK.

The IGEP SMARC iMX6 uses a 1V8 voltage levels for I2C buses. In some cases, bidirectional voltage translators
should be necessary to adapt voltage levels between ICs. It is important to say that an EEPROM is connected
to I2C3.(address 0x50) and MMPF0100 is connected to I2C2 (address 0x08).

In the next example (page 46 of SMARC Design Guide V_IO=1V8).
