CRC GENERATION
To validate the data transmitted from the DS2405, the bus master may generate a CRC value from the
data as it is received. This generated value is compared to the value stored in the last 8 bits of the
DS2405. If the two CRC values match, the transmission is error-free.
The equivalent polynomial function of this CRC is:
CRC = x
8 + x5 + x4 + 1
For more details, see the Book of DS19xx iButton Standards.
CUSTOM DS2405
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 special order parts. Contact your Dallas Semiconductor sales representative for
more information.
