M35045-XXXSP/FP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35045-XXXSP/FP is a TV screen display control IC. It uses a
silicon gate CMOS process and is housed in a 20-pin shrink DIP
package (M35045-XXXSP) or a 20-pin shrink SOP package
(M35045-XXXFP).
For M35045-001SP/FP that is a standard ROM version of M35045-
XXXSP/FP respectively, the character pattern is also mentioned.
