NOTES:
1. All voltages are referenced to ground.
2. V
PUP
= external pull–up 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 communica-
tions.
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 pull–up 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 counter inputs are designed for interfacing to mechanical switches and piezo sensors. If interfacing to digital
circuits, one should use an open–drain driver.
11. A lower impedance pull–up, e. g., for reed switches, can be achieved by connecting an external resistor from the
counter input to V
BAT
.
12.Read and write scratchpad (all 32 bytes) at V
BAT
of 3.0 V.
