LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
WAKEUP1 A10 C8 - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low-power modes. A pulse with a
duration > 45 ns wakes up the part. This pin does not have an
internal pull-up.
WAKEUP2 C9 E5 - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low-power modes. A pulse with a
duration > 45 ns wakes up the part. This pin does not have an
internal pull-up.
WAKEUP3 D8 - - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low-power modes. A pulse with a
duration > 45 ns wakes up the part. This pin does not have an
internal pull-up.

RTC
RTC_ALARM A11 A10 C3 129
[11]
O O RTC controlled output. This pin has an internal pull-up. The
reset state of this pin is LOW after POR. For all other types of
reset, the reset state depends on the state of the RTC alarm
interrupt.

[8]
- I Input to the RTC 32 kHz ultra-low power oscillator circuit.
RTCX2 B8 B7 B5 126
[8]
- O Output from the RTC 32 kHz ultra-low power oscillator circuit.
Crystal oscillator pins
XTAL1 D1 C1 B1 12
[8]
- I Input to the oscillator circuit and internal clock generator
circuits.
XTAL2 E1 D1 C1 13
[8]
- O Output from the oscillator amplifier.
Power and ground pins
