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.
