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.
