HD66781_1124769

•  Drive 262,144 TFT-color 240RGB x 320 dot graphics display in combination with HD66783 (a-Si
TFT panel) or HD667P21 (low-temperature poly-Si TFT panel)
•  Output signals to control HD66783, which incorporates a power supply integrated circuit and a gate
driver on a single chip.
•  Output signals to control a low-temperature poly-Si TFT panel with an incorporated gate driver
(combined use with HD667P21)
•  System interface
  High-speed bus interface with 8-/9-/16-/18-bit data bus
  Serial Peripheral Interface (SPI) 
•  Interfaces for moving picture display 
  RGB interface with 6-/16-/18-bit data bus (VSYNC, HSYNC, DOTCLK, ENABLE, PD17-0)
  VSYNC interface (System interface + VSYNC)
•  High-speed burst RAM write function
•  Compliant to single address mode for DMA transfer that controls data bus occupation ratio when transferring data from external SRAM
•  Window address function to write data to a rectangular area of RAM specified by the window address
  Interfaces for moving picture display, which write data to a rectangular RAM address area
  Reduce data transfer by transferring only the data for the moving picture display area 
  Simultaneous display of moving picture area and still picture area that displays the contents of internal RAM
  Resizing function (contraction rate: x1/2, x1/4 / magnification rate: x2, x4)
•  Various functions to control color display
