CRC GENERATION
To validate the registration number transmitted from the DS2411, the bus master can generate a CRC
value from the 8-bit family code and unique 48-bit serial number as it is received. If the CRC matches the
last 8 bits of the registration number, the transmission is error free.
The equivalent polynomial function of this CRC is: CRC = x
CUSTOM DS2411
Customization of a portion of the unique 48-bit serial number by the customer is available. Dallas
Semiconductor will register and assign a specific customer ID in the 12 most significant bits of the 48-bit
field. The next most significant bits are selectable by the customer as a starting value, and the least
significant bits are non-selectable and will be automatically incremented by one. Certain quantities and
conditions apply for these custom parts. Contact your Maxim/Dallas Semiconductor sales representative
for more information.
