SPLC780D
16COM/40SEG CONTROLLER/DRIVER
1. GENERAL DESCRIPTION
2. FEATURES
The SPLC780D, 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 SPLC780D
─ 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
SPLC780D is able to display up to two 8-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}
onfidenUse ^{On rank.}
─ Character font 5 x 10 dots: 4 characters
 4-bit or 8-bit MPU interfaces
 Direct driver for LCD: 16 COMs x 40 SEGs
 Duty factor (selected by program):
─ 1/8 duty: 1 line of 5 x 8 dots
─ 1/11 duty: 1 line of 5 x 10 dots
─ 1/16 duty: 2 lines of 5 x 8 dots / line
 Built-in power on automatic reset circuit
 Built-in oscillator circuit (with external resistor)
