I2C Address Mapping

There are four I2C interfaces used in SK EVM board:

  • SoC_I2C0 Interface: SoC I2C[0] is connected to Board ID EEPROM, User Expansion Connector Header, USB PD controller and PMIC
  • SOCI2C1 Interface: SoC I2C[1] is connected to Test Automation Header, Current Monitors (x6), Temperature Sensors (x2), Audio Codec, HDMI Transmitter & GPIO Port Expander (x2).
  • SOCI2C2 Interface: SoC I2C[2] is connected to the User Expansion Connector Header and both the CSI Camera connectors (Flex and MIPI).
  • MCUI2C0 Interface: MCU I2C[0] is connected to the MCU Header and PMIC.

Figure 2-33 depicts the I2C tree, and Table 2-37 provides the complete I2C address mapping details present on the AM62A Low Power SK EVM.
