PIN DESCRIPTION

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 Maxim 1-Wire protocol. The external power

supply is required, extending the operating voltage range of the device below typical 1-Wire devices.

1-Wire is a registered trademark of Maxim Integrated Products, Inc.
