Draft Version 0.1 Character / Graphic TFT LCD Controller RA8875 1. Description RA8875 is a text/graphic mixed display with 2 layers TFT LCD controller. It is designed to meet the requirement of middle size TFT module up to 800x480 pixels with characters or 2D graphic application. Embedded 768KB display RAM provides user a flexible solution for display buffer of almost application. Besides, the interface of external serial flash is optional to provide the up to 32x32pixels font bitmap for BIG5/GB coding. For graphic usage, RA8875 supports a 2D Block Transfer Engine(BTE) that is compatible with 2D BitBLT function for processing the mass data transfer. The advanced geometric speed-up engine provides user an easy way to draw the programmable geometric shapes by hardware, like line, square, circle and ellipse. Besides, for different end-user applications, many powerful functions are integrated with RA8875, such as scroll function, floating window display, graphic pattern and font enlargement function. These functions will save user a large of software effort during development period. RA8875 is a powerful and cheap choice for color display application. To reduce the system cost, RA8875 provides low cost and easy-to-use 8080/6800 parallel MCU interface. Because of the powerful hardware speed-up function embedded in it, less data transfer is needed so more efficiency is improved, RA8875 also provides serial SPI/I2C I/F with ultra-low pin-count. Useful device controller, such as flexible 4-wire touch panel controller, PWM for adjusting panel back-light are also included to reduce the system cost for customer. With the RA8875 design-in, user can achieve an easy-to-use, low-cost and high performance system comparing with the other solution. 2. Features Support Text/Graphic Mixed Display Mode. Embedded 768KB DDRAM. Color Depth TFT: 256/65K Colors. Supporting TFT 8/16 bpp Generic RGB Interface. Supporting TFT Panel Size: 800x480 Pixels 2 Layers @ 256 Colors. 800x480 Pixels 1 Layer @ 64K Colors. 480x272 Pixels 2 Layers @ 64K Colors. Supporting MCU Interface : 8080/6800 with 8/16 Data Bus Width I2C or 3/4-wire SPI I/F. Powerful Block Scrolling Function for Vertical or Horizontal Direction. Embedded 10KB Character ROM with Font Size 8x16 Dots and Supporting Character Sets of ISO/IEC 8859-1/2/3/4. External Serial Flash/ROM SPI I/F Supporting. Supporting Genitop Inc. UNICODE/BIG5/GB Serial font ROM with 16x16/24x24/32X32 dots Font Size. Font Enlargement Function X1, X2, X3, X4 for Horizontal/Vertical Direction. Font Vertical Rotation Mode Function.
