Dot Matrix LCD Controller Driver
SED1220 Series
I
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
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.
