DATA SHEET µPD6464A,6465 ON-SCREEN CHARACTER DISPLAY CMOS LSI FOR 12-LINE, 24-COLUMN DECK-TYPE VCR MOS INTEGRATED CIRCUIT The µPD6464A,6465 are CMOS LSIs for on-screen character display that control various display systems (such as tape counters) including the program screens of deck-type VCRs and LD players. These LSIs are used in combination with a microcomputer. It can display characters each consisting of 12 (horizontal) by 18 (vertical) dots. Some chinese characters and some pictograms can also be displayed by combining two or more characters. The µPD6464A,6465 include a power-ON clear function and a video RAM batch clear command that mitigate the workload of the host microcomputer.
