Overview

The LC7986C is a low-power CMOS IC that incorporates dot-matrix character generator, display controller and driver functions in a single device, and realizes ideal for use in portable equipment containing LCD displays.

Also, the CMOS process realizes easy expansion to control displays of up to 80 characters by adding LC7930N or LC7931D display drivers.
