The Microchip Technology Inc.24AA025E64 is a 2Kb Serial EEPROM with a preprogrammed IEEE EUI-64 MAC Address. The device is organized as two blocks of 128 x 8-bit memory with a 2-wire serial interface. Low voltage design permits operation down to 1.7V, with maximum standby and active currents of only 1 uA and 1 mA, respectively. The 24AA025E64 also has a page write capability for up to sixteen bytes of data. The 24AA025E64 is available in the standard 8-pin SOIC, 6-lead SOT-23.
