About the Toshiba T6963C LCD Controller

The Toshiba T6963C graphics controller chip is designed to control small to medium size graphic Liquid Crystal Display modules (LCD). It may be interfaced with a number of different 8-bit micro-processor units (MPU) such as the Z-80 or the 80C51/80C52.

It provides the necessary interface between the MPU and the video RAM (VRAM). It also generates the necessary timing and data signals for the liquid crystal driver circuits. It has a 128 character Character-Generator ROM (CG-ROM) and has the capability to control upto 64K bytes of external display RAM (VRAM). This VRAM may be allocated for text, graphics and external character-generator RAM (i.e. a user definable character generator). The T6963C can support a wide variety of LCD formats and has the ability to combine text and graphics data on to the LCD. A number of character attribute functions are also available.
