NOTES:
1. All voltages are referenced to ground.
2. VPUP = external pull-up voltage.
3. Input load is to ground.
4. Read data setup time refers to the time the host must pull the 1-Wire bus low to read a bit. Data is
guaranteed to be valid within 1 s of this falling edge.
5. Capacitance on the data pin could be 800 pF when power is first applied. If a 5 k
Ω resistor is used to
pull up the data line to VPUP, 5 s after power has been applied the parasite capacitance will not affect
normal communications.
6. The reset low time (tRSTL) should be restricted to a maximum of 960 s, to allow interrupt signaling,
otherwise, it could mask or conceal interrupt pulses.
7. VIH is a function of the external pull-up resistor and VPUP.
8. Under certain low voltage conditions VILMAX may have to be reduced to as much as 0.5V to always
guarantee a Presence Pulse. VIL is a function of VPUP and the reset low time.
9. During write operations to the EEPROM the voltage on the 1-Wire bus must not fall below 2.8V. The
EEPROM write cycle takes max. 10 ms.
10. The optimal sampling point for the master is as close as possible to the end time of the tRDV period
without exceeding tRDV. For the case of a Read-one time slot, this maximizes the amount of time for
the pull-up resistor to recover the line to a high level. For a Read-zero time slot it ensures that a read
will occur before the fastest 1-Wire device releases the line (tRELEASE = 0).
