SED1240 Series

LCD Controller Driver

SSC5000Series

■ DESCRIPTION

The dot-matrix LCD controller driver SED1240 series is designed to display characters and capable of displaying

up to 64 characters, 6 user-defined characters and 160 symbols using 4- or 8-bit or serial data sent from the

microcomputer.

The built-in character generator ROM is equipped with up to 544 types of character fonts, which consist of 5 × 8

dots respectively, enabling the maximum consecutive calls of 256 types by switching register options. This enables

various character fonts to be applied to each purpose or country, etc., further widening the use of this IC. The user-

defined character RAM for 6 characters of 5 × 8 dots is also built in, enabling display of high degree of freedom

through the symbol register.

Thanks to its ultra-low power consumption, sleep and standby modes, it can operate handy equipment with the

minimum power demand.

■ FEATURES

■ Built-in liquid crystal drive power circuit

Power boosting and voltage regulating circuits,

voltage followers (× 4), bias switching command

available, built-in resistance for power regulating

circuit

■ Built-in electronic volume function

■ Low power demand:
