Preliminary data sheet
7.8.1.1 Standard UARTs
7.8.1.2 High-speed UARTs
7.8.1 UARTs
7.8.2 SPI serial I/O controller
The LPC3220/30/40/50 contains seven UARTs. Four are standard UARTs, and three are
high-speed UARTs.
The four standard UARTs are compatible with the INS16Cx50. These UARTs support
rates up to 460800 bit/s from a 13 MHz peripheral clock.
Features
The three high-speed UARTs are designed to support rates up to 921600 bit/s from a
13 MHz peripheral clock for on-board communication in low noise conditions. This is
accomplished by changing the over sampling from 16 to 14 and altering the rate
generation logic.
Features
The LPC3220/30/40/50 has two Serial Peripheral Interfaces (SPI). The SPI is a 3-wire
serial interface that is able to interface with a large range of serial peripheral or memory
devices (SPI mode 0 to 3 compatible slave devices).

Each standard UART has 64 byte Receive and Transmit FIFOs.
Receiver FIFO trigger points at 16, 32 , 48 , and 60 Bytes.
Transmitter FIFO trigger points at 0, 4 , 8, and 16 Bytes.
Register locations conform to the “550” industry standard.
Each standard UART has a fractional rate pre-divider and an internal baud rate
generator.
The standard UARTs support three clocking modes: on, off, and auto-clock. The
auto-clock mode shuts off the clock to the UART when it is idle.
UART 6 includes an IrDA mode to support infrared communication.
The standard UARTs are designed to support data rates of (2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800) bit/s.
Each UART includes an internal loopback mode.
Each high-speed UART has 64 byte Receive and Transmit FIFOs.
Receiver FIFO trigger points at 1, 4, 8, 16, 32, and 48 Byte.
Transmitter FIFO trigger points at 0, 4, and 8 Byte.
Each high-speed UART has an internal baud rate generator.
The high-speed UARTs are designed to support data rates of (2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, 921600) bit/s.
The three high speed UARTs only support (8N1) 8-bit data word length, 1-stop bit, no
parity, and no flow control as a the communications protocol.
Each UART includes an internal loopback mode.
