DS1923: Hygrochron Temperature/Humidity Logger iButton with 8kB Data Log Memory
41 of 52
Master-to-Slave
For a
write-one
time slot, the voltage on the data line must have crossed the V
TH
threshold before the write-one
low time t
W1LMAX
is expired. For a
write-zero
time slot, the voltage on the data line must stay below the V
TH
threshold until the write-zero low time t
W0LMIN
is expired. The voltage on the data line should not exceed V
ILMAX
during the entire t
W0L
or t
W1L
window. After the V
TH
threshold has been crossed, the DS1923 needs a recovery time
t
REC
before it is ready for the next time slot.
