DS2502-E48 Overview
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.
DS2502-E48 Key Features
- Factory programmed 48-bit node address chip with 768 bits user-programmable OTPEPROM municates with the economy of one s
- 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 ali
- Built-in multidrop controller ensures patibility 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 municates 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
