Silicon serial number
Unique ID is provided on the VULCAN using DS2401 enhanced silicon serial number.
The DS2401 consists of 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
via the 1-Wire protocol that requires only a single data lead and a ground return. The
IXP425 processor’s pin GPIO14 is used to emulate the serial 1-Wire interface to the
DS2401.
