§ Meets the node identification requirements of  
IEEE Standard 1394-1995 (FireWireä )  
§ Unique, factory-lasered and tested 64-bit  
registration number (8-bit family code 89H +  
36-bit serial number + 12-bit UniqueWare  
identifier 5E7H + 8-bit CRC tester) assures  
absolute traceability because no two parts are  
alike  
§ Built-in multidrop controller ensures  
compatibility with other MicroLAN products  
§ Device is an “add only” memory where  
additional data can be programmed into  
EPROM without disturbing existing data  
§ Reduces control, address, data, power and  
programming signals to a single pin  
§ Directly connects to a single port pin of a  
microprocessor and communicates at up to  
16.3k bits per second

GLOBAL INDENTIFIER DESCRIPTION  
The DS2502-E64 is a variant of the DS2502 1024-bit Add-Only Memory. It differs from the standard  
DS2502 in its custom ROM family code 89H, and the UniqueWare Identifier 5E7 in place of the upper 12  
bits of the standard ROM serialization field. Otherwise, the electrical and logical behavior is identical to  
that of the DS2502. For technical details please refer to the DS2502 data sheet. The first 32 bytes of the  
DS2502-E64’s EPROM memory contain a globally unique 64-bit node address (EUI-64) and are write-  
protected. The data structure follows the conventions of UniqueWare devices using Default Data  
Structure (Figure 1).
