MAX31826
1-Wire Digital Temperature Sensor
with 1Kb Lockable EEPROM
64-Bit ROM Code
Each device contains a unique 64-bit code stored in ROM
(Figure 3). The least significant 8 bits of the ROM code
contain the devices 1-Wire family code, 3Bh. The next 48
bits contain a unique serial number. The most significant
8 bits contain a cyclic redundancy check (CRC) byte that
is calculated from the first 56 bits of the ROM code. See
the CRC Generation section for a detailed explanation
of the CRC bits. The 64-bit ROM code and associated
ROM function control logic allow the device to operate as
a 1-Wire device using the protocol detailed in the 1-Wire 
Bus System section.
