Option Multi 1- Wire Bus S0470C
This option
Multi 1-Wire
reference
S0470C
allows the reading of all 1-wire devices with the possibility to
have several devices on the same bus.
This option Multi 1-wire cannot be used with the
EaseLoc
application but can be directly
controlled with an
EGM
development.

Active or resistive pullup choice is configurable.

Except for t
F1
, all 1-Wire timing specifications and t
APUOT
are derived from the same timing circuit.
Therefore, if one of these parameters is found to be off the typical value, it is safe to assume that all these
parameters deviate from their typical value in the same direction and by the same degree.
6
These values apply at full load, i.e., 1nF at standard speed and 0.3nF at overdrive speed. For reduced
load, the pulldown slew rate is slightly faster.
7
Fall time high-to-low (t
F1
) is derived from P
DSRC
, referenced from 2.97 V
DC
to 0.33 V
DC
.
