6.1.1 4KB EEPROM (Board Identity Memory)

The Processor Module and LCD Module boards each contain a single 4KB EEPROM provided on I2C1 that contains the board specific information and allows the processor to automatically detect which board is connected and the version of that board. Other hardware specific data can be stored on this memory device as well. The WP pin on the EEPPROM device should be pulled to GND before writing to the device. Note that over writing the pre-programmed data in the EEPROM will inhibit TI software from running as-is.

The part number of the memory device is pn#CAT24C256WI-G. For details on the data in this memory, see Section 5.
