LPC2361/62
Single-chip 16-bit/32-bit MCU
7.14 UARTs
The LPC2361/2362 each contain four UARTs. In addition to standard transmit and receive
data lines, UART1 also provides a full modem control handshake interface.
The UARTs include a fractional baud rate generator. Standard baud rates such as
115200 Bd can be achieved with any crystal frequency above 2 MHz.
7.14.1 Features
• 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.
• Built-in fractional baud rate generator covering wide range of baud rates without a
need for external crystals of particular values.
• Fractional divider for baud rate control, auto baud capabilities and FIFO control
mechanism that enables software flow control implementation.
• UART1 equipped with standard modem interface signals. This module also provides
full support for hardware flow control (auto-CTS/RTS).
• UART3 includes an IrDA mode to support infrared communication.
7.15 SPI serial I/O controller
The LPC2361/2362 each contain one SPI controller. SPI is a full duplex serial interface
designed 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 8 bits to 16 bits of data to the slave, and
the slave always sends 8 bits to 16 bits of data to the master.
7.15.1 Features
• Compliant with SPI specification
• Synchronous, serial, full duplex communication
• Combined SPI master and slave
• Maximum data bit rate of one eighth of the input clock rate
• 8 bits to 16 bits per transfer
7.16 SSP serial I/O controller
The LPC2361/2362 each contain two SSP controllers. The SSP controller is capable of
operation on a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and
slaves on the bus. Only a single master and a single slave can communicate on the bus
during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits
to 16 bits of data flowing from the master to the slave and from the slave to the master. In
practice, often only one of these data flows carries meaningful data.
7.16.1 Features
• Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National
Semiconductor Microwire buses
