must be unconnected
To always allow communication through the 1-Wire or wire port, the voltage on V
CC
must be
approximately 3-wire port, the voltage on V
CC
must be approximately 0.2V above the voltage on V
BATB
.
Otherwise the DS2404 will retain data, but will not allow any access.
The V
BATB
pin is normally connected to any standard 3V lithium cell or other energy source. As V
CC
falls
below V
BATB
, the power switching circuit allows V
BATB
to provide energy for maintaining clock
functionality and data retention. No communication can take place while V
BATB
is greater than V
CC
.
During power-up, when V
CC
reaches a value of approximately 0.2V above V
BATB
, the power switching
circuit connects V
CC
and disconnects V
BATB
. If the oscillator is on, no communication can take place
until V
CC
has stayed approximately 0.2V above V
BATB
for 123 ± 2 ms. During power-down, the falling
V
CC
must pass the range from V
BATB
to 0V in no less than 100 ns for the power switching circuit to
function properly.
