I2C Interface

The AM275x EVM Features four I2C Interfaces from the AM275x SoC:

  • I2C0 Interface: The I2C0 Port of the AM275x SoC is mapped to the Board ID EEPROM, USB PD Controller, PCM6240 (x2) , TAD5212 (x4), CDCE6214, Current Monitors (x7), Temperature Sensor, CPSW RGMII Expansion Connectors (x2) and GPIO Expanders (x2)
  • I2C3 Interface: The I2C3 Port of the AM275x SoC is mapped to the Audio Expansion Connector 1 (AEC 1)
  • I2C5 Interface: The I2C5 Port of the AM275x SoC is mapped to the Audio Expansion Connector 2 (AEC 2)
  • WKUP_I2C0 Interface: The WKUP_I2C0 Port of the AM275x SoC is mapped to the PMIC for Q&A Watchdog.

The Bootmode IO Expander I2C pins are mapped to the I2C1 port of the XDS110 Debugger through the BOOTMODE_I2C signals.
