Notes upon power-on sequence
It requires more than 600
s (between 0.0 V to 5.0 V) to rise voltage upon power on in order to prevent the
device malfunction caused by the overshooting in the built-in voltage step-down circuit.
After the supply voltage is stable (voltage is risen) , it takes 600
s until internal supply is stable. Hold the input
to the INITX pin during that period.
If it takes less than 600
s (between 0.0 V to 5.0 V) for power up, it requires 2 ms* until internal supply is stable
after voltage supply is stable (voltage is risen) . Hold the input to the INITX pin during that period.
* : In case of which it takes less than 600
s (between 0.0 V to 5.0 V) to rise voltage, the time to make internal
power supply stable is proportional to the capacitance value of the bypass capacitor for the pin C.
It takes 2 ms if the pin C = 4.7
F ; 4 ms if the pin C = 9.4 F.
