RV5C387A
6.2 Connection of INTRA, INTRB or INTRC Pin
The INTRA, INTRB or INTRC pin follows the N-channel open drain output logic and contains no protective diode on
the power supply side. As such, it can be connected to a pull-up resistor of up to 5.5 volts regardless of supply
voltage.
6.3 Connection of 32KOUT Pin
The 32KOUT pin follows the Nch. open drain output and contains no protective diode on the power supply side. As
such, it can be connected to a device with a supply voltage of up to 5.5 volts regardless of supply voltage, provided
that such connection involves considerations for the supply current requirements of a pull-up resistor, which can be
roughly calculated by the following equation:
I=0.5
×(VDD or VCC)/Rp

*1) Depending on whether the INTRA, INTRB or INTRC pin is to be
used during battery backup, it should be connected to a pull-up
resistor at the following different positions:
1) Position A in the left diagram when it is not to be used during
battery backup.
2) Position B in the left diagram when it is to be used during
battery backup.
