25AA02E48 2K SPI Bus Serial EEPROM with EUI-48? Node Identity (12/4/2008)

The Microchip Technology Inc. 25AA02E48 is a 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25AA02E48 is available in the standard 8-lead SOIC and 6-lead SOT-23 packages.

NOTE 1: The Date Code is the manufacturing date code for standard products and is represented by the first 4 digits of the trace code "YYWWNNN". YY signifies the last two digits of the year. NOTE: 2000 would be marked “00”. WW represents the working week. NOTE: The week of January 1 would be marked “01” ). If the six-digit YWWNNN code cannot fit on the package, the full seven-digit code should appear on the next higher level of packaging.
