DS2502–E64
IEEE EUI–64 Node Address Chip
DS2502–E64
PRELIMINARY
021998 1/2
FEATURES
IEEE–approved factory programmed 64–bit node
address chip (EUI–64) with 768 bits user–program-
mable OTP–EPROM communicates with the econ-
omy of one signal plus ground
Meets the node identification requirements of IEEE
Standard 1394–1995 (FireWire
TM
)
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 tes-
ter) assures absolute traceability because no two
parts are alike
Built–in multidrop controller ensures compatibility
with other MicroLAN
TM
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 program-
ming signals to a single pin
Directly connects to a single port pin of a microproces-
sor and communicates at up to 16.3k bits per second
Presence detector acknowledges when reader first
applies voltage

GLOBAL IDENTIFIER 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 Unique-
Ware Identifier 5E7 in place of the upper 12 bits of the
standard ROM serialization field. Otherwise, the electri-
cal 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 com-
pany ID value 006035H. A 16–bit CRC ends the data
record. The remaining bytes of the 32–byte memory
page remain unprogrammed. Neither the 40–bit exten-
sion identifier nor the 24–bit company ID are related to
