FEATURES
IEEE-approved factory programmed 64-bit
node address chip (EUI-64) with 768 bits
user-programmable OTP-EPROM
communicates with the economy of one
signal plus ground
Meets the node identification requirements of
IEEE Standard 1394-1995 (FireWire
)
Unique, factory-lasered and tested 64-bit
registration number assures absolute
traceability because no two parts are alike
Built-in multidrop controller ensures
compatibility with other 1-Wire 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
Presence detector acknowledges when reader
first applies voltage
Low cost TO-92 or TSOC surface mount
packages
Reads over a wide voltage range of 2.8V to
6.0V from -40°C to +85°C; programs at
11.5V to 12.0V from -40°C to +50°C

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 5E7h 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.
