DATA SHEET MOS INTEGRATED CIRCUIT µPD6461, 6462 CMOS LSI CHIP FOR CAMCORDER ON-SCREEN CHARACTER DISPLAY (12 ROWS × 24 COLUMNS) The µPD6461, 6462 are CMOS LSI chips designed to provide on-screen character display for camcorders.
When combined with a microcontroller, the µPD6461, 6462 control the display of the characters displayed in the viewfinder (count, time, date, etc.) and the recording of characters onto video tape (time, date, etc.).
Each character is created using 12 (width) × 18 (height
D6461 Features
* Maximum number of characters: 12 rows × 24 columns (288 characters)
* Number of character patterns : 256 (µPD6461)/128 (µPD6462) (stored in ROM). Each pattern can be changed by specifying a mask code option.
* Character size : One dot per line or one dot per two lines
