1-WIRE CRC GENERATION BLOCK DIAGRAM –

HARDWARE CONFIGURATION
Because the 1-Wire bus has only a single line, it is important that each device on the bus be able to drive
it at the appropriate time. To facilitate this, each device attached to the 1-Wire bus must connect to the
bus with open-drain or tri-state output drivers. The DS2760 used an open-drain output driver as part of
the bi-directional interface circuitry shown in Figure 15. If a bi-directional pin is not available on the bus
master, separate output and input pins can be tied together.
The 1-Wire bus must have a pull-up resistor at the bus-master end of the bus. For short line lengths, the
value of this resistor should be approximately 5 k
. The idle state for the 1-Wire bus is high. If, for any
reason, a bus transaction must be suspended, the bus MUST be left in the idle state in order to properly
resume the transaction later. If the bus is left low for more than 120
μ
s, slave devices on the bus begin to
interpret the low period as a Reset Pulse, effectively terminating the transaction.
