CMOS IC
LC7982A
LCD Dot Matrix Graphics Display Controller
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.
