SPLC783A
16COM/80SEG CONTROLLER/DRIVER
1. GENERAL DESCRIPTION
3. FEATURES
The SPLC783A, a dot-matrix LCD controller and driver from
Character generator ROM: 10880 bits
SUNPLUS, is a unique design for displaying alpha-numeric,
─ Character font 5 x 8 dots: 192 characters
Japanese-Kana characters and symbols. The SPLC783A
─ Character font 5 x 10 dots: 64 characters
provides two types of interfaces to MPU: 4-bit and 8-bit interfaces.
Character generator RAM: 512 bits
The transferring speed of 8-bit is twice faster than 4-bit. A single
─ Character font 5 x 8 dots: 8 characters
SPLC783A is able to display up to two 16-character lines. By
cascading with SPLC100 or SPLC063, the display capability can
l be extended. The CMOS technology ensures the power saves in
tia ly the most efficient way and the performance keeps in the highest
n n rank.
