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.

■ FEATURES

48 characters + 4 user-defined characters + 64 symbols

■ CGROM (for up to 256 characters), CGRAM (4 characters), and symbol register (64 symbols)

■ Number of display columns × number of lines

(12 columns + 1 column for signal) × 4 lines + 52 symbols: SED1230

(12 columns + 1 column for signal) × 3 lines + 52 symbols: SED1231

(12 columns + 1 column for signal) × 2 lines + 52 symbols: SED1232

16 columns × 2 lines + 64 symbols:

■ CR oscillating circuit (incorporating C and R)

■ High-speed MPU interface

SED1233

Interfacing with both 68 series and 80 series MPU

Interfacing in 4 bits/8 bits
