Overview
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) dots.
Kanji characters and graphic symbols can also be displayed by using two or more characters.
The µPD6461, 6462 are compatible with color viewfinders and can output character signals to three channels, the RGB channel for the color viewfinder and the VC1 and VC2 channels for the recording system and monitor terminal.
The µPD6461, 6462 also have a power-on clear function and video RAM batch clear command, enabling the number of operations assigned to the microcontroller to be reduced.
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 (field) • Number of character colors : 8 • Background : No background, minimum background, or overall background can be selected for the entire screen, together with rimming ON/OFF function.
Any one of 8 different colors is selectable as the background color and together with the rim color (black or white) selectable per screen.
• Dot matrix : Each character consists of 12 (width) × 18 (height) dots.
There is no gap between adjacent characters.
• Blinking : Blinking can be turned on/off for each character.
The blinking ratio is 1:1.
The blinking frequency can be selected from approx.
1 Hz, 2 Hz, and 0.
5 Hz for the entire screen.
• Reversed characters : Specified characters can be displayed in rev...
