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 ref.
Factory programmed 48-bit node address chip with 768 bits user-programmable OTPEPROM 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
