Fast communication chip
7.9 LCD controller
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.
7.9.1
Features
AHB bus 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

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.
7.10 Ethernet
The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC
designed to provide optimized performance through the use of DMA hardware
acceleration. Features include a generous suite of control registers, half or full duplex
operation, flow control, control frames, hardware acceleration for transmit retry, receive
packet filtering and wake-up on LAN activity. Automatic frame transmission and reception
with scatter-gather DMA off-loads many operations from the CPU.
