M35074-XXXSP

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS

DESCRIPTION

The M35074-XXXSP is a character pattern display control IC can

display on the digital camera, the digital video, the digital televi-

sion, the CRT display, the liquid crystal display and the plasma

display.

A character color and a character background color can be cho-

sen from 128 kinds of colors per character.

It uses a silicon gate CMOS process and it housed in a 20-pin

shrink DIP package (M35074-XXXSP).

For M35074-002SP that is a standard ROM version of M35074-

XXXSP respectively, the character pattern is also mentioned.
