1. GENERAL DESCRIPTION
The SPLC780D, a dot-matrix LCD controller and driver from
SUNPLUS, is a unique design for displaying alpha-numeric,
Japanese-Kana characters and symbols. The SPLC780D
provides two types of interfaces to MPU: 4-bit and 8-bit interfaces.
SunpusConidenia
The transferring speed of 8-bit is twice faster than 4-bit. A single
SPLC780D is able to display up to two 8-character lines. By
cascading with SPLC100 or SPLC063, the display capability can
be extended. The CMOS technology ensures the power saves in
the most efficient way and the performance keeps in the highest
rank.
