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
• AnVSS = A0VSS AnVREFM = A0VREFM
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.
• AnVDD = A0VDD
• AnVREFP = A0VREFP
• 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:
