LPC185x/3x/2x/1x
32-bit ARM Cortex-M3 microcontroller
• 15 gray-level monochrome, 3375 color STN, and 32 K color palettized TFT support.
• 1, 2, or 4 bits-per-pixel (bpp) palettized displays for monochrome STN.
• 1, 2, 4, or 8 bpp palettized color displays for color STN and TFT.
• 16 bpp true-color non-palettized for color STN and TFT.
• 24 bpp true-color non-palettized for color TFT.
• Programmable timing for different display panels.
• 256 entry, 16-bit palette RAM, arranged as a 128 32-bit RAM.
• Frame, line, and pixel clock signals.
• AC bias signal for STN, data enable signal for TFT panels.
• Supports little and big-endian, and Windows CE data formats.
• LCD panel clock can be generated from the peripheral clock, or from a clock input pin.
7.15.9 Ethernet
Remark: The ethernet controller is available on parts LPC185x and LPC183x. Ethernet is
not available on parts LPC182x and LPC181x.
7.15.9.1 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.
• Support for IEEE 1588 time stamping and IEEE 1588 advanced time stamping (IEEE
1588-2008 v2).
7.16 Digital serial peripherals
7.16.1 UART
Remark: The LPC185x/3x/2x/1x 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.
