Type Description

VDDA(1V8)

63

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)

VDDA(3V3)

23, 43, 51 I

7

I

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

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 available on LPC2109/01, LPC2119/01, and LPC2129/01 only.
