Product data sheet
6.10.2 UART features available in LPC213x/01 only
6.11.1 Features
6.12 SPI serial I/O controller
6.11 I
The LPC2131/32/34/36/38 each contain two I
The I
(SCL), and a serial data line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver or a transmitter with the
capability to both receive and send information (such as memory)). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I
controlled by more than one bus master connected to it.
This I
The LPC2131/32/34/36/38 each contain one SPI controller. The SPI is a full duplex serial
interface, designed to be able to handle multiple masters and slaves connected to a given
bus. Only a single master and a single slave can communicate on the interface during a
given data transfer. During a data transfer the master always sends a byte of data to the
slave, and the slave always sends a byte of data to the master.

C-bus serial I/O controller
Built-in baud rate generator.
Standard modem interface signals included on UART1. (LPC2134/36/38 only)
The LPC2131/32/34/36/38 transmission FIFO control enables implementation of
software (XON/XOFF) flow control on both UARTs and hardware (CTS/RTS) flow
control on the LPC2134/36/38 UART1 only.
Fractional baud rate generator enables standard baud rates such as 115200 to be
achieved with any crystal frequency above 2 MHz.
Auto-bauding.
Auto-CTS/RTS flow-control fully implemented in hardware (LPC2134/36/38 only).
Standard I
Easy to configure as Master, Slave, or Master/Slave.
Programmable clocks allow versatile rate control.
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
