Table 16: RH850/F1KM-S4 Power supply architecture with mixed supply 5V & 3.3V
Case 7 – Mixed Supply 5V & 3.3V
Condition
REGVCC = 5V
EVCC = 5V
BVCC = 3.3V
A0VREF = 3.3V
A1VREF = 5V
Port Function
AP0 – Port usable with analog or digital function
P8 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V. When analog input terminal is over 3.3V,
do not include the input into an AD scan group.
P9 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V. When analog input terminal is over 3.3V,
do not include the input into an AD scan group.
AP1 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
P18 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
P19 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
Limitation
Analog port function limitation applies to P8, P9, P18 and P19
