NOTES:
1.
All voltages are referenced to ground.
2.
V
PUP
= external pullup voltage.
3.
Input load is to ground.
4.
An additional reset or communication sequence cannot begin until the reset high time has expired.
5.
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
μ
s of this falling edge.
6.
Capacitance on the data pin could be 800 pF when power is first applied. If a 5 k
resistor is used to
pull up the data line to V
PUP
, 5
μ
s after power has been applied the parasite capacitance will not affect
normal communications.
7.
The reset low time (t
RSTL
) should be restricted to a maximum of 960
μ
s, to allow interrupt signaling,
otherwise, it could mask or conceal interrupt pulses.
8.
V
IH
is a function of the external pullup resistor and V
PUP
.
9.
Under certain low voltage conditions V
ILMAX
may have to be reduced to as much as 0.5V to always
guarantee a Presence Pulse.
10.
The Copy Scratchpad takes 5 ms maximum during which the voltage on the 1-Wire bus must not fall
below 2.8V.
11.
During the execution of the Copy Scratchpad command the DS2433 automatically erases the memory
locations to be written to. No extra steps need to be taken by the bus master.
