SED1200F  
Dot Matrix LCD Controller Driver  
1/8 or 1/16 Duty Dot Matrix Drive  
20 Character Simultaneous Display  
Built in Character Generator ROM and RAM  
DESCRIPTION  
The SED1200F is a dot matrix LCD controller/driver with a built in CG (character generator).  
The circuit consists of a CG ROM which contains 160 different characters, 4 words CG RAM, 20 words display  
data RAM and logic functions to operate a 20 character display. Additional characters may be used by writing  
CG data to the 4 words CG RAM.  
The device also contains the resistor array for the LCD power supply. The SED1200F is fabricated Silicon Gate  
CMOS process and features very low power dissipation. This makes the device very desirable for applications  
in hand held, portable and other battery powered instruments.  
FEATURES  
1/8 or 1/16 duty cycle dot matrix drive  
20 character simultaneous display  
Built in character generator ROM and RAM
