V
18
17, 49 I 1.8V Core Power Supply: This is the power supply voltage for internal circuitry.
V
18A
63 I
Analog 1.8V Core Power Supply: This is the power supply voltage for internal circuitry. This
should be nominally the same voltage as V18 but should be isolated to minimize noise and error.
V

23, 43,
51
I 3.3V Pad Power Supply: This is the power supply voltage for the I/O ports.
V
3A
7I
Analog 3.3V Pad Power Supply: This should be nominally the same voltage as V3 but should
be isolated to minimize noise and error. Level on this pin is used as a reference for AD convertor.
