SED1278  
CMOS DOT MATRIX LCD CONTROLLER DRIVER  
DESCRIPTION  
The SED1278 is a character LCD controller-driver, capable of driving displays as large as 2 lines of 8  
characters (5 × 8 pixels), with minimum external components.  
The SED1278 has an internal CGROM consisting of 240 characters (5 × 7) plus the underline cursor, JIS,  
ASCII, and eight user-programmable characters in RAM.  
The SED1278 has 40 segment output and 16 common output built-in. Thus, one chip is capable of displaying  
up to 16 characters. The SED1278 can display one line of 48 characters using an SED1681F (80-bit output)  
as an expansion segment driver.  
The SED1278 is fabricated using a silicon gate CMOS technology process and features very low power  
dissipation. This makes the device suitable for handheld and portable applications.
