UC1538 display driver library

The UC1538 and UC1538C display controllers are supported by the RAMTEX UC1611 display driver library package.
Full GUI display driver code. Processor and C compiler independent C source code.

UC1538 display controller characteristics

Below is a brief introduction to the main characteristics for the UC1538 Grey-level display controller (seen from a software driver design viewpoint).

For information about the UC1538 driver software support please go to the library description.

UC1538 device type

  • Grey-level color display controller for use in small embedded systems with on-chip frame buffer and LCD screen driver.
  • The UC1538 supports LCD screens with a size up to 240 x 160 pixels (WxH)
  • On-chip LCD driver with voltage generator and software controlled LCD contrast regulation.

Frame buffer

  • Grey-level pixel resolution (bits per pixel): 2-bit, and 1 bit.
  • UC1538 frame buffer organization: 240 Grey-level pixels on scan line, 160 lines.
  • Frame buffer storage use vertical storage units with 8 or 4 pixels.

Processor interfaces on UC1538

  • UC1538 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 UC1538
    • SPI bus: 4-wire: /CS, CD, SDIN, SCLK.
    • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 uses a 9 bit byte frame where first bit is CD
    • I2C bus: 2-wire: SDIN, SCLK
  • The bus interfaces are all supported by the UC1538 display driver software package.

Special UC1538 hardware features:

  • 0-180, 90-270 degree frame buffer rotation with hardware support
  • Support for screen driver contrast regulation in hardware.
  • Full driver software support.
