ST7628 display controller characteristics

Below is a brief introduction to the main characteristics for the ST7628 RGB display controller (seen from a software driver design viewpoint).

For information about the ST7628 driver software support please go to the library description.

ST7628 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and LCD screen driver.
  • The ST7628 supports LCD screens with a size up to 98 x 70 pixels (WxH)
  • On-chip LCD driver with voltage generator and software controlled contrast regulation.

Frame buffer

  • RGB pixel resolution (bits per pixel): 16-bit.
  • ST7628 frame buffer organization: 98 RGB pixels on scan line, 70 lines.

Processor interfaces on ST7628

  • ST7628 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 ST7628
    • SPI bus: 4-wire: /CS, DC, SDIN, SCLK.
