USB_DM 25 19 13
[8]
F- USB_DM — USB bidirectional D line. (LPC1345/46/46
only.)
USB_DP 26 20 14
[8]

XTALIN 8 6 4
[9]
- - Input to the oscillator circuit and internal clock generator
circuits. Input voltage must not exceed 1.8 V.
XTALOUT 9 7 5
[9]
- - Output from the oscillator amplifier.
V
DDA
59 - - - - Analog 3.3 V pad supply voltage: This should be
nominally the same voltage as V
DD
but should be isolated
to minimize noise and error. This voltage is used to power
the ADC. This pin should be tied to 3.3 V if the ADC are
not used.
VREFN 48 - - - - ADC negative reference voltage: This should be
nominally the same voltage as V
SS
but should be isolated
to minimize noise and error. Level on this pin is used as a
reference for ADC.
