XTAL2

Output from the oscillator ampliﬁer.

VSS

6, 18, 25, 42,

Ground: 0 V reference.

VSSA

Analog Ground: 0 V reference. This should nominally be the same voltage

as VSS, but should be isolated to minimize noise and error.

VSSA_PLL

PLL Analog Ground: 0 V reference. This should nominally be the same

voltage as VSS, but should be isolated to minimize noise and error.

V18

17, 49

1.8 V Core Power Supply: This is the power supply voltage for internal

circuitry.

V18A

Analog 1.8 V 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.

23, 43, 51

3.3 V Pad Power Supply: This is the power supply voltage for the I/O ports.

V3A

Analog 3.3 V Pad Power Supply: This should be nominally the same

voltage as V3 but should be isolated to minimize noise and error.
