M35072-XXXFP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35072-XXXFP is a character pattern display control IC can display on the display monitor. It can display 2 pages (24 characters × 12 lines per 1 page) at the same time. It uses a silicon gate CMOS process and it housed in a 20-pin shrink SOP package . For M35072-002FP that is a standard ROM version of M35072XXXFP respectively, the character pattern is also mentioned.
