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

• Background

: 8

: 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

• Blinking

: Each character consists of 12 (width) × 18 (height) dots. There is no gap between

adjacent characters.

: 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.

: Specified characters can be displayed in reverse video.

• Reversed characters

• Character signal output

: Character signals can be output to three channels. Output mode (1) (RGB + BLK, V^C1

+ VBLK1, and VC2 + VBLK2) or output mode (2) (R + RBLK, B + BBLK, and G + GBLK) can

be selected by specifying a mask option. For output mode 1, three output formats are

available for the V^C1and VC2 channels (options A, B, and C).

: Video RAM batch clear command and power-on clear function

• Clearing of video RAM

• Interface with a microcontroller : 8-bit serial input supporting variable word length (LSB first or MSB first can be selected

by specifying a mask option.)

• Supply voltage

: Low-voltage operation possible (supply voltage range: 2.7 to 5.5 V)
