Read Time Slots
The host generates read time slots when data is to be read from the DS2436. A read time slot is initiated
when the host pulls the data line from a logic high level to logic low level. The data line must remain at a
low logic level for a minimum of 1
s; output data from the DS2436 is then valid for the next 14 s
maximum. The host therefore must stop driving the I/O pin low in order to read its state 15
s from the
start of the read slot (see Figure 9). By the end of the read time slot, the I/O pin will pull back high via the
external pullup resistor. All read time slots must be a minimum of 60
s in duration with a minimum
recovery time of 1
s between individual read slots.
Figure 10 shows that the sum of TINIT, TRC, and TSAMPLE must be less than 15
s. Figure 11 shows that
system timing margin is maximized by keeping TINIT and TRC as small as possible and by locating the
master sample time towards the end of the 15
s period.
