UPD6466

DATA SHEET MOS INTEGRATED CIRCUIT µPD6466 ON-SCREEN CHARACTER DISPLAY CMOS IC FOR 512-CHARACTER, 12-ROW, 24-COLUMN, CAMERA-CONTAINED VCR The µPD6466 is a CMOS LSI for on-screen character display, and can be used in combination with a microcomputer to display the tape counter, time, and date in the view finder of a video camera, or the time of a video tape, messages such as dates on pictures, and channel number on a TV screen. Characters are displayed in 12 (horizontal) by 18 (vertical) dots. Two or more characters can be combined to display Kanji (Japanese characters) and symbols. This LSI supports color view finders and is provided with three sets of character output signals (RGB output: for color view finder, VC1 output: for recording (or monitor pin), VC2 output: for monitor pin (or recording)). In addition, the µPD6466 is also equipped with a power-ON clear function and a video RAM batch clear command so that it can mitigate the workload of the microcomputer. The command format of this LSI is identical to that of the existing models, the µPD6461 and 6462, and therefore, the µPD6466 is compatible with the existing models, and the software resources for the existing models can be used.
