RA8876 TFT display driver library

The RA8876 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

RA8876 display controller characteristics

Below is a brief introduction to the main characteristics for the RA8876 RGB display controller (seen from a software driver design viewpoint).

For information about the RA8876 driver software support please go to the library description.

RA8876 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
  • The RA8876 supports TFT screens with a size up to 1280 x 1024 pixels (WxH)
  • On-chip TFT driver with voltage generator

Frame buffer

  • RGB pixel resolution (bits per pixel): 8-bit, 16-bit, 24 bit.
  • RA8876 frame buffer organization: 1280 RGB pixels on scan line, 1024 lines.

Processor interfaces on RA8876

  • RA8876 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 RA8876
    • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 SPI-4 is separate MOSI and MISO lines. Address is specified as first SPI byte.
    • I2C bus: 2-wire: SDIN, SCLK
    • In SPI bus mode the frame buffer memory can not be read.
  • The bus interfaces are all supported by the RA8876 display driver software package.

Special RA8876 hardware features:

  • Frame Buffer size set equal to Display size..
  • 0-180, 90-270 degree frame buffer rotation with hardware support. Portrait mode, landscape mode.
  • Full driver software support.
