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
μ
s; output data from the DS2436 is then valid for the next 14
μ
s
maximum. The host therefore must stop driving the I/O pin low in order to read its state 15
μ
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
μ
s in duration with a minimum
recovery time of 1
μ
s between individual read slots.
Figure 10 shows that the sum of T
INIT
, T
RC
, and T
SAMPLE
must be less than 15
μ
s. Figure 11 shows that
system timing margin is maximized by keeping T
INIT
and T
RC
as small as possible and by locating the
master sample time towards the end of the 15
μ
s period.
