Type Description

VSS

3, 9, 26, I

ground: 0 V reference

38, 54, 67,

79, 93,

103, 107,

111, 128

VSSA

139

I

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)

138

I

PLL analog ground; 0 V reference. This should nominally be the same voltage

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

VDD(1V8)

37, 110 I

1.8 V core power supply; this is the power supply voltage for internal circuitry.

VDDA(1V8)

143

I

analog 1.8 V core power supply; this is the power supply voltage for internal

circuitry. This should be nominally the same voltage as VDD(1V8) but should be

isolated to minimize noise and error.

VDD(3V3)

2, 31, 39, I

51, 57, 77,

94, 104,

112, 119

3.3 V pad power supply; this is the power supply voltage for the I/O ports

VDDA(3V3)

14

I

analog 3.3 V pad power supply; this should be nominally the same voltage as

VDD(3V3) but should be isolated to minimize noise and error

[1] SSP interface is available on LPC2212/01 and LPC2214/01 only.
