
Supports 4 Transparent BLT Modes

• Bitmap Transparency
• Pattern Transparency
• Source Transparency
• Destination Transparency
Rectangle Clipping

Fast Line Draw Engine with styled pattern

Fast Rectangle Fill Engine

256MB frame buffer with linear addressing

64x64x2 bit-mapped mono hardware cursor

•
VGA Output (DB15)
Supports 135 MHz triple RAMDACs for 1280 x 1024 x 75 Hz display

Supports 24-bit pixel depth

Supports interlaced or non-interlaced output

•
TTL Output
Conforms with VESA Flat Panel Display Interface FPDI-1B

Supports up to 1600x1200 pixel display resolutions

Uses Internal CRT Controller for display modes settings

Supports 12-, 18-, and dual 12-bit Interface (1 pixel/clock)

Table 3-12 describes the pin signals of the Video interface, which uses a 44-pin, right-angle header with 2
rows, odd/even sequence (1, 2), and 0.079" (2mm) pitch.

Description
TFT Shift Clock – This clock signal provides the timing for transferring digital
pixel data.
TFT Data Enable – This signal indicates valid data on any of the FP [23:0] lines.
TFT Line Pulse – This signal is the digital monitor equivalent of HSYNC.
TFT Frame Marker – This signal is the TFT monitor equivalent of VSYNC.
