SED1220 Series

Dot Matrix LCD Controller Driver

●12 chara x 3 line (5 x 8 dot)

●Built-in Character Generator ROM and RAM

●Built-in Power Supply Circuit for LCD

■OVERVIEW

SED1220 is a dot matrix LCD controller/driver for character display. Using 4bits data, 8bits data or serial data being

provided from the micro computer, it displays up to 24 characters, 4 user defined characters and up to 120 symbols.

Up to 256 types of built-in character generator ROMs are prepared. Each character font is consisted of 5 × 8 dots.

It also contains the RAM for displaying 4 user defined characters each font consisting of 5 × 8 dots. It is symbol

minimum power consumption with its low power consumption design, standby and sleeping mode.

■FEATURES

● Built-in data display RAM – 36 characters + 4 user defined characters + 120 symbols.

● CG ROM (For up to 256 characters), CG RAM (for 4 characters) and symbol register (for 120 symbols).

● No. of display digit and lines
