DS2502-E48

19-5071; 12/09 DS2502-E48 48-Bit Node Address Chip www.maxim-ic.com FEATURES  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  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 1-Wire is a registered trademark of Maxim Integrated Products, Inc.
