Overview

The LC7982A is an LCD dot matrix graphics display

controller IC. It stores display data sent from an 8-bit

microcontroller in external display RAM and generates

dot matrix LCD drive signals. Applications can select

either of two modes: graphics mode, in which each bit in

external RAM controls the on/off state of an individual

pixel (dot) on the LCD, and character mode, in which

character codes are stored in external RAM and the dot

pattern is generated using the built-in character generator

ROM. Thus the LC7982A can support a wide range of

applications. The LC7982A is fabricated in a CMOS

process, and in conjunction with a CMOS microcontroller,

can implement low-power LCD display systems. This

device differs from the LC7981 only in the data stored in

the built-in character generator ROM.
