UC1698 display controller characteristics

Below is a brief introduction to the main characteristics for the UC1698 RGB display controller (seen from a software driver design viewpoint).

For information about the UC1698 driver software support please go to the library description.

UC1698 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and LCD screen driver.
  • The UC1698 supports LCD screens with a size up to 160 x 128 pixels (WxH)
  • On-chip LCD driver with voltage generator and software controlled contrast regulation.

Frame buffer

  • RGB pixel resolution (bits per pixel): 16-bit.
  • UC1698 frame buffer organization: 160 RGB pixels on scan line, 128 lines.

Processor interfaces on UC1698

  • UC1698 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))
