SED1230 Series
Dot Matrix LCD Controller Driver
SSC5000Series
■12 Character × 4 Line (5 × 7 dot)
■Built-in Character Generator ROM and RAM
■Built-in Power Supply Circuit for LCD
■ DESCRIPTION
The SED1230 Series is a dot matrix LCD controller driver for character display, and can display a maximum of 48
characters, 4 user-defined characters, and a maximum of 64 symbols by means of 4-bit, 8-bit or serial data sent
from a microcomputer.
A built-in character generator ROM is prepared for 256 character types, and each character font consists of 5 × 7
dots. A user-defined character RAM for four characters of 5 × 7 dots are incorporated, and a symbol register is also
incorporated. With these, it is possible to apply this Series to display with a high degree of freedom. This Series
can operate handy units with a minimum power consumption by means of its low power consumption and standby
mode.
The SED1230 Series are classified into SED1230, SED1231, SED1232, and SED1233 depending on the duty of
use and the number of display columns.
