DESCRIPTION
The DS2411 silicon serial number is a low-cost, 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). The DS2411’s 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 Dallas Semiconductor’s 1-Wire protocol. The
external power supply is required, extending the operating voltage range of the device below typical
1-Wire devices.
