MAC Address Click Board™

Product Code: MIKROE-2733

The MAC Address Click Board™ provides a unique node address for your application. It also has 1Kbit of writable EEPROM memory. MAC Address click carries the 24AA025E64 2K I2C Serial EEPROM with EUI-64™ node identity. The click is designed to run on either 3.3V or 5V power supply. MAC Address click communicates with the target microcontroller over I2C interface. 24AA025E64 Features The Microchip Technology Inc. 24AA025E64 is a 2Kb Serial EEPROM with a pre-programmed 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.
