SED1278
CMOS DOT MATRIX LCD CONTROLLER DRIVER
s 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.
