LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
[1]
5 V tolerant pad (no built-in pull-up resistor) providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.
[2]
5 V tolerant pad (no built-in pull-up resistor) providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control. If
configured for an input function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns.
[3]
Open-drain 5 V tolerant digital I/O I
2
C-bus 400 kHz specification compatible pad. It requires external pull-up to provide an output
functionality.
[4]
5 V tolerant pad (no built-in pull-up resistor) providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog
input function. If configured for an input function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns. When
configured as an ADC input, digital section of the pad is disabled.
[5]
5 V tolerant pad (no built-in pull-up resistor) providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog
output function. When configured as the DAC output, digital section of the pad is disabled.
[6]
5 V tolerant pad with built-in pull-up resistor providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.
The pull-up resistor’s value typically ranges from 60 k
to 300 k
.
[7]
Pad is designed in accordance with the Universal Serial Bus (USB) specification, revision 2.0 (Full-speed and Low-speed mode only).
[8]
5 V tolerant pad providing digital input (with TTL levels and hysteresis) function only.
[9]
Pad provides special analog functionality.
[10] When unused, the RTCX1 pin can be grounded or left floating. For lowest power leave it floating.
The other RTC pin, RTCX2, should be left floating.

I
Analog 3.3 V power supply:
This should be nominally the same
voltage as V
DD
but should be isolated to minimize noise and error.
This voltage is only used to power the on-chip ADC(s) and DAC.
ADC reference voltage:
This should be nominally less than or equal
to the V
DD
voltage but should be isolated to minimize noise and error.
Level on this pin is used as a reference for ADC(s) and DAC.
RTC power supply voltage:
3.3 V on this pin supplies the power to
the RTC.
