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 36 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
register allows character display with high degree of
freedom. This handy equipment can be operated with
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).
