LPC4350/30/20/10

32-bit ARM Cortex-M4/M0 microcontroller

• LCD panel clock may be generated from the peripheral clock, or from a clock input

pin.

7.17.8 Ethernet

Remark: The Ethernet peripheral is available on parts LPC4350/30. See Table 2.

7.17.8.1

Features

• 10/100 Mbit/s

• DMA support

• Power management remote wake-up frame and magic packet detection

• Supports both full-duplex and half-duplex operation

– Supports CSMA/CD Protocol for half-duplex operation.

– Supports IEEE 802.3x flow control for full-duplex operation.

– Optional forwarding of received pause control frames to the user application in

full-duplex operation.

– Back-pressure support for half-duplex operation.

– Automatic transmission of zero-quanta pause frame on deassertion of flow control

input in full-duplex operation.

• Supports IEEE1588 time stamping and IEEE 1588 advanced time stamping (IEEE

1588-2008 v2).

7.18 Digital serial peripherals

7.18.1 UART1

The LPC4350/30/20/10 contain one UART with standard transmit and receive data lines.

UART1 also provides a full modem control handshake interface and support for

RS-485/9-bit mode allowing both software address detection and automatic address

detection using 9-bit mode.

UART1 includes a fractional baud rate generator. Standard baud rates such as 115200 Bd

can be achieved with any crystal frequency above 2 MHz.

7.18.1.1

Features

• Maximum UART data bit rate of 8 MBit/s.

• 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.

• Auto baud capabilities and FIFO control mechanism that enables software flow

control implementation.

• Equipped with standard modem interface signals. This module also provides full

support for hardware flow control.

• Support for RS-485/9-bit/EIA-485 mode (UART1).
