LPC2377/78
Single-chip 16-bit/32-bit microcontrollers
[1]
5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis.
[2]
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input. When configured as a DAC input,
digital section of the pad is disabled.
[3]
5 V tolerant pad providing digital I/O with TTL levels and hysteresis and analog output function. When configured as the DAC output,
digital section of the pad is disabled.
[4]
Open-drain, 5 V tolerant digital I/O pad compatible with I
2
C-bus 400 kHz specification. It requires an external pull-up to provide output
functionality. When power is switched off, this pin connected to the I
2
C-bus is floating and does not disturb the I
2
C lines. Open-drain
configuration applies to all functions on this pin.
[5]
Pad provides digital I/O and USB functions (LPC2378 only). It is designed in accordance with the
USB specification, revision 2.0
(Full-speed and Low-speed mode only).
[6]
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
[7]
5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
[8]
Pad provides special analog functionality.
[9]
When the main oscillator is not used, connect XTAL1 and XTAL2 as follows: XTAL1 can be left floating or can be grounded (grounding
is preferred to reduce susceptibility to noise). XTAL2 should be left floating.
[10] If the RTC is not used, these pins can be left floating.
[11] Pad provides special analog functionality.
[12] Pad provides special analog functionality.
[13] Pad provides special analog functionality.
[14] Pad provides special analog functionality.
[15] Pad provides special analog functionality.
[16] Pad provides special analog functionality.

3.3 V DC-to-DC converter supply voltage:
This is the power supply for the on-chip
DC-to-DC converter only.
analog 3.3 V pad supply voltage:
This should be nominally the same voltage as
V
DD(3V3)
but should be isolated to minimize noise and error. This voltage is used to
power the ADC and DAC.
ADC reference:
This should be nominally the same voltage as V
DD(3V3)
but should
be isolated to minimize noise and error. The level on this pin is used as a reference
for ADC and DAC.
RTC pin power supply:
3.3 V on this pin supplies the power to the RTC peripheral.
