DS2411R+U

The DS2411R+U is an Electronic Registration Number with external power supply. It provides an absolutely unique identity that can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller). This registration number is a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC and an 8-bit family code (01h). Data is transferred serially through the 1-Wire® protocol. The external power supply is required, extending the operating voltage range of the device below typical 1-Wire devices.

• Unique, factory-lasered and tested 64-bit registration number
• <lt/>1µA Standby current
• Built-in multidrop controller enables multiple DS2411s to reside on a common 1-wire network
• Multidrop compatible with other 1-wire products
• 8-bit family code identifies device as DS2411 to 1-wire master
• Directly connects to a single-port pin of a microprocessor and communicates at up to 15.4kbps
• Overdrive mode boosts communication speed to 125kbps
