Product data sheet
6.10.1 Features
6.7.2 Fast I/O features available in LPC213x/01 only
6.8.1 Features
6.8.2 ADC features available in LPC213x/01 only
6.9.1 Features
6.10 UARTs
6.8 10-bit ADC
6.9 10-bit DAC
The LPC2131/32 contain one and the LPC2134/36/38 contain two ADCs. These
converters are single 10-bit successive approximation ADCs with eight multiplexed
channels.
This peripheral is available in the LPC2132/34/36/38 only. The DAC enables the
LPC2132/34/36/38 to generate variable analog output.
The LPC2131/32/34/36/38 each contain two UARTs. In addition to standard transmit and
receive data lines, the LPC2134/36/38 UART1 also provides a full modem control
handshake interface.

Fast I/O registers are located on the ARM local bus for the fastest possible I/O timing.
All GPIO registers are byte addressable.
Entire port value can be written in one instruction.
Mask registers allow single instruction to set or clear any number of bits in one port.
Measurement range of 0 V to 3.3 V.
Each converter capable of performing more than 400000 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 (LPC2134/36/38 only).
Every analog input has a dedicated result register to reduce interrupt overhead.
Every analog input can generate an interrupt once the conversion is completed.
10-bit digital to analog converter.
Buffered output.
Power-down mode available.
Selectable speed versus power.
16 B Receive and Transmit FIFOs.
Register locations conform to 16C550 industry standard.
Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B
