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.

FEATURES
• Number of display characters : 12 rows, 24 columns (288 characters)
• Types of character : 512 types (ROM). Changeable by using mask code option.
• Character size : Can be expanded up to four-fold in vertical and horizontal directions independently, in units of lines.
• Number of character colors : 8 colors
• Framing : Framing or no framing, or white or black framing selectable in screen units.
• Dot matrix : 12 (horizontal) × 18 (vertical) dot configuration. No gap between adjacent characters.
• Blinking : Blinking can be turned ON/OFF in character units. The blinking ratio is 1:1.
The blinking frequency can be selected from about 1 Hz, about 2 Hz, and about 0.5 Hz in screen unit.
• Character color reversing function : The color of the character and that of the background can be reversed.
• Character left and right reverse : Left and right can be reversed for display in character units.
• Background : No background, blank background, or filled background selectable in screen units.
• Blue back function : Blue or white can be selected as the background.
• Signal output : 3 sets (output (1) R, G, B + BLK/VC1 + VBLK1/VC2 + VBLK2 and output (2) R + RBLK/B + BBLK/G + GBLK selectable by command)
When output (1) is selected, VC1 and VC2 outputs can be selected from three types.
• Video RAM data clear : Implemented by video RAM batch clear command or by clear function on
power-ON.
• Interface with microcomputer : 8-bit variable word length serial input (LSB first/MSB first selectable by
command)
• Supply voltage : Supports low voltage (2.7 to 5.5 V)
• Process : CMOS low power consumption
