Voltage distribution
The table shows the required device power supply pins and their function:
Device supply pin
Function
REGVDD
Supply for the device internal regulators for the digital logic.
EVDD
Supply for ports of AWO and ISO area.
A0VREF
Supply for ports and analog functions of ADC0.
Additionally one power supply for MainBoard can be selected:
Supply voltage
Function
VDDIOF
IO supply voltage for components located on a connected
mainboard.
•
For each of the above voltages, the voltage source can be selected from
Voltage1
(typ. 5.0V) or
Voltage2
(typ. 3.3V) by the jumpers CN12, CN13,
CN15, CN16, respectively by the jumpers CN11 and CN14.
