SED1278F/D  
Dot Matrix LCD Controller Driver  
● 1/8, 1/11 or 1/16 Duty Dot Matrix Drive  
● Built-in Character Generator ROM and RAM (  
ROM 240 characters  
RAM 8 characters  
)
● Maximum Simultaneous Display of 80 Characters  
(With extension LCD driver)  
■ DESCRIPTION  
The SED1278F/D is a dot matrix LCD controller/driver which is dedicated to character display. It is capable of  
displaying up to 80 characters under 4-bit/8-bit MPU control.  
The built-in character generator ROM has an extended capacity of 240 different characters, each being generated  
in a 5×10 dots font compatible with a 1/11 duty. In addition, the SED1278F/D contains 64 bytes of character  
generator RAM in which the user can store 8 different characters, each consisting of 558 dots. These memory  
features offer high flexibility in character display.  
The guaranteed minimum LCD driving voltage is 3V, and this makes the SED1278F/D suitable for driving low  
voltage LCDs.  
■ FEATURES  
● Display RAM .............................. 80 bytes (80 characters)  
● Character generator ROM.......... 240 characters (Able to 256 characters)  
● Character generator RAM .......... 8 characters  
● Built-in CR oscillator, Built-in power-on reset circuit  
● Maximim display dimension ....... 40 characters52 lines, 80 characters51 line  
(When accompanied with SED1181F /D , SED1681F /D  
)
