1.3.2 Power Supply Pin Configuration of RH850/F1KM-S4
The following shows power supply pin configuration. Do not open any power and GND terminals even if those are
internally connected.
The EVCC supply pins are internally connected
The BVCC supply pins are internally connected. (when available on the device).
The EVSS pins are internally connected.
The BVSS pins are internally connected. (when available on the device).
AWOVSS and ISOVSS are internally connected.
Others are not internally connected.
1.3.3 Power Supply Pin Architecture of RH850/F1KM-S4
The RH850/F1KM-S4 supports different power supply architectures. The power supply architecture depends on the
chosen RH850/F1KM-S4 device, application requirements and the use case.
Some common conditions apply to the supply of the RH850/F1KM-S4:
REGVCC = EVCC = VPOC to 5.5V
BVCC = VPOC to REGVCC (when available on the device)
A0VREF = 3.0V to 5.5V
A1VREF = 3.0V to 5.5V (when available on the device)
AWOVSS = ISOVSS = EVSS = BVSS = A0VSS = A1VSS = 0V
The following figure and the different cases describe the impact to the ADC ports and the ports with analog/digital
function depending on the power supply architecture. In addition, it describes the limitations to these ports.

Note: The BVCC and A1VREF supply pin availability depends on the chosen device.
