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  
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.
