1.1.2 Power Supply Pin Configuration of RH850/F1KM-S1
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 EVSS pins are internally connected.
• AWOVSS and ISOVSS are internally connected.
• Others are not internally connected.
1.1.3 Power Supply Pin Architecture of RH850/F1KM-S1
The RH850/F1KM-S1 supports different power supply architectures. The power supply architecture depends on the
application requirements and the use case.
Some common conditions apply to the supply of the RH850/F1KM-S1:
• REGVCC = EVCC = VPOC to 5.5V
• A0VREF = 3.0V to 5.5V
• AWOVSS = ISOVSS = EVSS = A0VSS = 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.
