SSD1322 display controller characteristics

Below is a brief introduction to the main characteristics for the SSD1322 Grey-level display controller (seen from a software driver design viewpoint).

For information about the SSD1322 driver software support please go to the library description.

SSD1322 device type

• Grey-level color display controller for use in small embedded systems with on-chip frame buffer and OLED screen driver.
• The SSD1322 supports OLED screens with a size up to 480 x 128 pixels (WxH)
• On-chip OLED driver with voltage generator and software controlled LCD contrast regulation.

Frame buffer

• Grey-level pixel resolution (bits per pixel): 4 bit.
• SSD1322 frame buffer organization: 480 Grey-level pixels on scan line, 128 lines.
• Frame buffer storage use 4 pixels in 2 horizontal bytes.

Processor interfaces on SSD1322

• SSD1322 parallel bus interface

  • Parallel bus types: 8080 bus type and 6800 bus type
  • Parallel bus size: 8 bit.
  • Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))

• Serial bus interfaces on SSD1322

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