Note
• Embedded 768K byte SRAM display buffer.
• 8/16-bit Intel 80 interface (used for display or register data).
• Chip select is used to select device. When inactive, any input data/command will be
• RGB: 8:8:8, 6:6:6, 5:6:5 (8:8:8 will be truncated to 16 or 18 bpp).
• YUV 4:2:2, 4:2:0 (Internal YUV to RGB Converter stored as 16 or 18 bpp).
• Active Matrix TFT interface.
• 16/18 bit-per-pixel (bpp) color depths.
• 16 bpp to 18 bpp conversion: Input data can be converted from 16 bpp to 18 bpp in one
ignored.
All input data must be internally converted to the same format before being stored in the
display buffer. Different data types can not be mixed within a common display buffer.
• 18/36-bit interface.
• Supports resolutions up to 800x480.
of three ways.
1. RGB (5:6:5) msb copying to create new lsb for the Red and Blue components.
2. Gamma Correction Look-Up-Tables: there are three, 64 position, 8-bit wide
3. RGB (5:6:5) stored in memory: LUT is by-passed. Copy msb to lsb for red and
This conversion is done prior to storing in memory, as this allows for 16 bpp and
18 bpp input data to be mixed.

LUT’s are placed on the display side and therefore do not affect the data stored in
memory.
