LPC2114/2124
Single-chip 16/32-bit microcontrollers
[1] SSP interface available on LPC2114/01 and LPC2124/01 only.
V
DDA(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 V
DD(1V8)
but should be
isolated to minimize noise and error.
V
DD(3V3)
23, 43, 51 I 3.3 V pad power supply; this is the power supply voltage for the I/O ports
V
DDA(3V3)
7 I analog 3.3 V pad power supply; this should be nominally the same voltage as
V
DD(3V3)
but should be isolated to minimize noise and error
