DS2401/DS2411

The DS2401 and DS2411 devices are 64-bit read only memory (ROM) "silicon serial number" devices from Dallas Semiconductor/Maxim. The devices are programmed by the manufacturer with a unique 48 bit serial number, an 8 bit product family code, and an 8 bit CRC. The family code is the same at 01h for both DS2401 and DS2411 devices. The stored data can be read from the devices through the Dallas 1-Wire protocol.
