Notes
1. All voltages refer to VDD as 0 V.
2. For voltages V1, V2, V3 and V4, be sure to keep the conditions of "VDD V1 V2 V3 V4" and "VDD VSS V5".
3. If the LSI is used outside the absolute maximum ratings, it may permanently break. Use under the electrical characteristics conditions is recommended for normal operation, otherwise, the LSI may malfunction, isadvantageously affecting itsreliability.


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.
