LPC178x/7x

32-bit ARM Cortex-M3 microcontroller

• Accept any size of data width per write: 8, 16 or 32-bit.

– 8-bit write: 1-cycle operation

– 16-bit write: 2-cycle operation (8-bit x 2-cycle)

– 32-bit write: 4-cycle operation (8-bit x 4-cycle)

7.13 LCD controller

Remark: The LCD controller is available on parts LPC1788/87/86/85.

The LCD controller provides all of the necessary control signals to interface directly to a

variety of color and monochrome LCD panels. Both STN (single and dual panel) and TFT

panels can be operated. The display resolution is selectable and can be up to 1024

 768

pixels. Several color modes are provided, up to a 24-bit true-color non-palettized mode.

An on-chip 512-byte color palette allows reducing bus utilization (i.e. memory size of the

displayed data) while still supporting a large number of colors.

The LCD interface includes its own DMA controller to allow it to operate independently of

the CPU and other system functions. A built-in FIFO acts as a buffer for display data,

providing flexibility for system timing. Hardware cursor support can further reduce the

amount of CPU time needed to operate the display.

7.13.1 Features

• AHB master interface to access frame buffer.

• Setup and control via a separate AHB slave interface.

• Dual 16-deep programmable 64-bit wide FIFOs for buffering incoming display data.

• Supports single and dual-panel monochrome Super Twisted Nematic (STN) displays

with 4-bit or 8-bit interfaces.

• Supports single and dual-panel color STN displays.

• Supports Thin Film Transistor (TFT) color displays.

• Programmable display resolution including, but not limited to: 320  200, 320  240,

640

 200, 640  240, 640  480, 800  600, and 1024  768.

• Hardware cursor support for single-panel displays.

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

pin.
