2.6.7.4 Board ID EEPROM

The AM62D Audio EVM board can be identified remotely from its version and serial number data stored on the on-board EEPROM.

Board ID memory AT24C512C-MAHM-T from Microchip is interfaced to the I2C0 port of the SoC and is configured to respond to address 0x54 programmed with the header description. I2C address of the EEPROM can be modified by driving the A2 pin to high and A1, A0 pins to LOW. The first 259 bytes of memory are preprogrammed with identification information for each board. The remaining 65277 bytes are available to the user for data or code storage.
