Note 2 : PC Card/CompactFlash Power Domain Group
•
•
•
This group of signals is in the PC Card/CompactFlash power domain group.
Supply voltage range is specified from 2.85 V to 3.6 V.
This is also the internally connected supply to the internal regulator. Hence pin #28 should be connected to the PC
Card/CompactFlash supply source.
Note 3 : Modem Power Domain Group
•
•
This group of I/O signals is in the MODEM power domain group.
Supply voltage range is specified from 1.8 V to 3.6 V.
Note 4 : Analogue Power Domain Group
This group of I/O signals is in the analogue power domain group (which supplies the oscillator and PLL).
•
Note 5 : USB Power Domain Group
•
•
This group signals is in the USB power domain group.
Supply voltage range is specified from 2.85 V to 3.6 V.
