The pins AWOVCL, AWOVSS and ISOVCL, ISOVSS are available on all devices to connect external capacitors.
1.1.2 Power Supply Pin Configuration of RH850/F1K Group
Depending on the device, the following power supply pin configuration applies:
The EVCC supply pins are internally connected.
1.1.3 Power Supply Pin Architecture of RH850/F1K Group
The RH850/F1K group supports different power supply architectures. The power supply architecture depends on the
chosen RH850/F1K group device, application requirements and the use case.
Some common conditions apply to the supply of the RH850/F1K group:
 REGVCC = EVCC = VPOC to 5.5V
 A0VREF = 3.0V to 5.5V
 A1VREF = 3.0V to 5.5V
 AWOVSS = ISOVSS = EVSS = 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.
