LPC2478
Single-chip 16-bit/32-bit microcontroller
[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 ADC 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.

external reset input:
A LOW on this pin resets the device, causing I/O
ports and peripherals to take on their default states, and processor
execution to begin at address 0. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
ground:
0 V reference for the digital IO pins.
