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.
