LPC2131/2132/2134/2136/2138
Single-chip 16/32-bit microcontrollers
6.10 General purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back, as well as the current state of the port pins.
6.10.1
Features
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.11 10-bit A/D converter
The LPC2131/32 contain one and the LPC2134/2136/2138 contains two analog to digital
converters. These converters are single 10-bit successive approximation analog to digital
converters with eight multiplexed channels.
6.11.1
Features
Measurement range of 0 V to 3.3 V.
Each converter capable of performing more than 400,000 10-bit samples per second.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on input pin or Timer Match signal.
Global Start command for both converters (LPC2134/2136/2138 only).
6.12 10-bit D/A converter
This peripheral is available in the LPC2132/2134/2136/2138 only. The D/A converter
enables the LPC2132/2134/2136/2138 to generate variable analog output.
6.12.1
Features
10 bit digital to analog converter.
Buffered output.
Power-down mode available.
Selectable speed versus power.
