ON-SCREEN CHARACTER DISPLAY CMOS IC FOR 512-CHARACTER,

12-ROW, 24-COLUMN, CAMERA-CONTAINED VCR

The information in this document is subject to change without notice.

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.

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
