  • The SSD1783 supports LCD screens with a size up to 132 x 160 pixels (WxH)
  • On-chip LCD driver with voltage generator and software controlled intensity regulation.

Frame buffer

  • RGB pixel resolution (bits per pixel): 8-bit, 16-bit, 18-bit.
  • SSD1783 frame buffer organization: 132 RGB pixels on scan line, 160 lines.

Processor interfaces on SSD1783

  • SSD1783 parallel bus interface
    • Parallel bus types: 8080 bus type and 6800 bus type
    • Parallel bus size: 8-bit, 16-bit.
    • Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))
  • Serial bus interfaces on SSD1783
    • SPI bus: 4-wire: /CS, DC, SDIN, SCLK
