Chapter 3 Power supply specification

3.1 Requirements for external power supply

connections

The user has to ensure a low resistive connection of all VSS pins on the PCB.

This specification denotes ground supply pins as:

• VSS = OSCVSS = REGnVSS = EnVSS = BnVSS = AnVSS = AnVREM =

CVSS = 0V

in the further text.

With

• EnVSS = E1VSS

• BnVSS = B0VSS

• REGnVSS = REG0VSS = REG1VSS = REG2VSS = REG3VSS

• AnVSS = A0VSS = A1VSSAnVREFM = A0VREFM = A1VREFM

The user has to ensure a low resistive connection of all VDD pins to the related

power supply. This specification denotes power supply pins as:

• EnVDD, BnVDD, FVDD, REGnVDD, OSCVDDCVDD, AnVDD and

AnVREFP.

in the further text.

With

• EnVDD = E0VDD = E1VDD

• BnVDD = B0VDD

• REGnVDD = REG0VDD = REG1VDD = REG2VDD = REG3VDD.

• AnVDD = A0VDD = A1VDD

• AnVREFP = A0VREFP = A1VREFP

• I/OVDD = AnVDD, EnVDD, B0VDD, FVDD, OSCVDD

3.2 Power area definitions

The device consists of the following power areas:

• AWO (Always On area)

• ISO0 (Isolated area 0)

• ISO1 (Isolated area 1)

The table below lists the related core and port voltage supply of each power

area:
