DS2431: 1024-Bit, 1-Wire EEPROM

Master-to-Slave

For a write-one time slot, the voltage on the data line must have crossed the VTH threshold before the write-one

low time tW1LMAX is expired. For a write-zero time slot, the voltage on the data line must stay below the VTH

threshold until the write-zero low time tW0LMIN is expired. For the most reliable communication, the voltage on the

data line should not exceed VILMAX during the entire tW0L or tW1L window. After the VTH threshold has been crossed,

the DS2431 needs a recovery time tREC before it is ready for the next time slot.
