... FUNCTIONAL DESCRIPTION 2.1 Principles of Operation The 25AA02E48 is a 256-byte Serial EEPROM designed to interface directly with the Serial Peripheral Interface (SPI) port of many of today’s popular microcontroller families, including Microchip’s PIC microcontrollers. It may also interface with microcon- trollers that do not have a built-in SPI port by using discrete I/O lines programmed properly in software to match the SPI protocol ...

... PRE-PROGRAMMED EUI-48™ NODE ADDRESS The 25AA02E48 is programmed at the factory with a globally unique, EUI-48™ and EUI-64™ compatible node address stored in the upper 1/4 of the array and write-protected through the STATUS register. The remaining 1,536 bits are available for application use. ...

... CS is required prior to any sequence being initiated. 4.2 Serial Output (SO) The SO pin is used to transfer data out of the 25AA02E48. During a read cycle, data is shifted out on this pin after the falling edge of the serial clock. 4.3 Write-Protect (WP) The WP pin is a hardware write-protect input pin. ...
