1. GENERAL DESCRIPTION
The SPLC783A, a dot-matrix LCD controller and driver from
SUNPLUS, is a unique design for displaying alpha-numeric,
Japanese-Kana characters and symbols. The SPLC783A
SunpusConidenia
provides two types of interfaces to MPU: 4-bit and 8-bit interfaces.
The transferring speed of 8-bit is twice faster than 4-bit. A single
SPLC783A is able to display up to two 16-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.
