LPC2470
Flashless 16-bit/32-bit microcontroller
[1]
5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis.
[2]
Either the I
2
S function or the LCD function is selectable, see
Table 19
,
Table 20
, and
Table 21
.
[3]
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input. When configured as a ADC input,
digital section of the pad is disabled.
[4]
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.
[5]
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.
[6]
Pad provides digital I/O and USB functions. It is designed in accordance with the
USB specification, revision 2.0
(Full-speed and
Low-speed mode only).
[7]
Either the USB OTG function or the LCD function is selectable, see
Table 19
,
Table 20
, and
Table 21
.
[8]
Either the trace function or the LCD function is selectable, see
Table 19
,
Table 20
, and
Table 21
.
[9]
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
[10] Either one of the external interrupts EINT1 to EINT3 or the LCD function is selectable, see
Table 19
,
Table 20
, and
Table 21
.
[11] Either one of the timer outputs MAT2[1] and MAT2[0] or the LCD function is selectable, see
Table 19
,
Table 20
, and
Table 21
.
[12] 5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
[13] Pad provides special analog functionality.
[14] 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.
[15] If the RTC is not used, these pins can be left floating.
[16] This pin has a built-in pull-up resistor.
[17] This pin has no built-in pull-up and no built-in pull-down resistor.

I
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 power supply:
3.3 V on this pin supplies the power to the RTC
peripheral.
