4.5.2 Board ID EEPROM

The AM263x LaunchPad has a I2C based 1Mbit EEPROM (CAT23M01WI-GT3) to store board configuration details. The Board ID EEPROM is connected to the I2C1 interface of the AM263x SoC. The default I2C address of the EEPROM is set to 0x52 by pulling up the address pin A1 and pulling down the address pin A2 to ground. The Write Protect pin for the EEPROM is by default pulled down to ground and therefore Write Protect is disabled.
