DS28EC20: 20Kb 1-Wire EEPROM
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. For the most reliable communication, 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
DS28EC20 needs a recovery time t REC before it is ready for the next time slot.
