特性

• 65,536 bits electrically programmable read only memory (EPROM)
• 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
• EPROM partitioned into 256-bit pages for randomly accessing packetized data records
• Each memory page can be permanently write-protected to prevent tampering
• Reduces control, address, data, power, and programming signals to a single data pin
• Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbps
• Overdrive mode boosts communication speed to 142kbps
• Low-cost PR35 or 8-pin SO surface-mount package
• 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
