碌
PD6461, 6462
CMOS LSI CHIP FOR CAMCORDER ON-SCREEN CHARACTER DISPLAY
(12 ROWS
脳
24 COLUMNS)
MOS INTEGRATED CIRCUIT
The
碌
PD6461, 6462 are CMOS LSI chips designed to provide on-screen character display for camcorders. When
combined with a microcontroller, the
碌
PD6461, 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)
脳
18 (height) dots. Kanji characters and graphic symbols can also be displayed
by using two or more characters. The
碌
PD6461, 6462 are compatible with color viewfinders and can output character signals
to three channels, the RGB channel for the color viewfinder and the V
C1
and V
C2
channels for the recording system and
monitor terminal.
The
碌
PD6461, 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
鈥?Maximum number of characters: 12 rows
脳
24 columns (288 characters)
鈥?Number of character patterns : 256 (
碌
PD6461)/128 (
碌
PD6462) (stored in ROM). Each pattern can be changed by
specifying a mask code option.
鈥?Character size
鈥?Number of character colors
鈥?Background
: One dot per line or one dot per two lines (field)
: 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.
鈥?Dot matrix
鈥?Blinking
鈥?Reversed characters
鈥?Character signal output
: Each character consists of 12 (width)
脳
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.
: Character signals can be output to three channels. Output mode (1) (RGB + BLK, V
C1
+ V
BLK1
, and V
C2
+ V
BLK2
) or output mode (2) (R + R
BLK
, B + B
BLK
, and G + G
BLK
) can
be selected by specifying a mask option. For output mode 1, three output formats are
available for the V
C1
and V
C2
channels (options A, B, and C).
鈥?Clearing of video RAM
: Video RAM batch clear command and power-on clear function
by specifying a mask option.)
鈥?Supply voltage
: Low-voltage operation possible (supply voltage range: 2.7 to 5.5 V)
鈥?Interface with a microcontroller : 8-bit serial input supporting variable word length (LSB first or MSB first can be selected
