DS2502-E48
48-Bit Node Address Chip
www.maxim-ic.com
FEATURES
§ Factory programmed 48-bit node address
chip with 768 bits user-programmable OTP-
EPROM communicates with the economy of
one signal plus ground
§ Provides valid MAC-48/EUI-48
ETHERNET address
§ 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
16.3kbps
§ 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

GLOBAL IDENTIFIER DESCRIPTION
The DS2502-E48 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.
