... Memory (EEPROM) organized as 256 words of eight bits each and is accessed via an I interface. In addition, AT24MAC402/602 incorporates an easy and inexpensive method to obtain a globally unique MAC or EUI address (EUI-48 or EUI-64). AT24MAC402 is an EUI-48 compatible device that contains a 48-bit EUI address, and AT24MAC602 is an EUI-64 compatible device that contains a 64-bit EUI address. ...

... Operations” on page 15. EUI Address Access: The AT24MAC402/602 utilizes an extended memory block containing a factory-programmed read-only EUI-48 or EUI-64 address respectively. Access to this memory block is obtained by beginning the device address word with a ‘1011’ (Bh) sequence. The behavior of the next three bits (A2, A1, and A0) remain the same as during a standard memory addressing sequence ...

... Page Write: The AT24MAC402/602 is capable of a 16-byte Page Write. A Page Write is initiated by the same method as a Byte Write, but the microcontroller does not send a Stop condition after the first data word is clocked in. Instead, after the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to fifteen more data words ...
