1.3.1 Power Supply Pin Overview of RH850/F1KM-S4
The devices of the RH850/F1KM-S4 have the following power supply pins:
• Power supply voltage REGVCC for the on-chip voltage regulators. The output voltage of the voltage
regulators is supplied to the digital circuits in each power domain.
• Power supply voltages EVCC and BVCC (depending on device pin count) for the I/O ports.
• Power supply voltages A0VREF and A1VREF (depending on the device pin count) for the A/D converters and
the separated I/O ports.
