UC1698 LCD display driver library

The UC1698, UC1698G, and UC1698U display controllers are supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

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))

• Serial bus interfaces on UC1698

  • SPI bus: 4-wire: /CS, DC, SDIN, SCLK.
  • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 uses a 9 bit byte frame where first bit is DC
• The bus interfaces are all supported by the UC1698 display driver software package.

Special UC1698 hardware features:

• 0-180, 90-270 degree frame buffer rotation with hardware support. Portrait mode, landscape mode.
• Software controlled intensity regulation.
• Full driver software support.
