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