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 Maxim 1-Wire® protocol. The external power supply is required, extending the operating voltage range of the device below typical 1-Wire devices.
