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).

The data record starts with a length byte (0CH) and the 4-byte UniqueWare Project ID 00001128H. The next eight bytes contain the EUI-64 global identifier (node address) which consists of an incrementing 40-bit extension identifier and the IEEE-assigned 24-bit company ...
