MITSUBISHI MICROCOMPUTERS M35070-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS DESCRIPTION The M35070-XXXSP/FP is a character pattern display control IC can display on the CRT display the liquid crystal display and the plasma display. 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 DIP package (M35070-XXXSP) or a 20-pin shrink SOP package (M35070-XXXFP). For M35070-002SP/FP that is a.

MITSUBISHI MICROCOMPUTERS M35070-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS DESCRIPTION The M35070-XXXSP/FP is a character pattern display control IC can display on the CRT display the liquid crystal display and the plasma display. 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 DIP package (M35070-XXXSP) or a 20-pin shrink SOP package (M35070-XXXFP). For M35070-002SP/FP that is a standard ROM version of M35070XXXSP/FP respectively, the character pattern is also mentioned.
