LPC2101/2102/2103
Single-chip 16-bit/32-bit microcontrollers
6.7 Fast 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.
LPC2101/2102/2103 introduce accelerated GPIO functions over prior LPC2000 devices:
GPIO registers are relocated to the ARM local bus for the fastest possible I/O timing.
Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
All GPIO registers are byte addressable.
Entire port value can be written in one instruction.
6.7.1
Features
Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.8 10-bit A/D converter
The LPC2101/2102/2103 contain one analog to digital converter. It is a single 10-bit
successive approximation analog to digital converter with eight channels.
6.8.1
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.
Every analog input has a dedicated result register to reduce interrupt overhead.
6.9 UARTs
The LPC2101/2102/2103 each contain two UARTs. In addition to standard transmit and
receive data lines, UART1 also provides a full modem control handshake interface.
Compared to previous LPC2000 microcontrollers, UARTs in LPC2101/2102/2103 include
a fractional baud rate generator for both UARTs. Standard baud rates such as 115200 can
be achieved with any crystal frequency above 2 MHz.
6.9.1
Features
16 byte Receive and Transmit FIFOs.
Register locations conform to ‘550 industry standard.
Receiver FIFO trigger points at 1, 4, 8, and 14 bytes
