Overview
The LC74732W is an on-screen display CMOS IC that
displays characters and patterns on a TV screen under the
control of a microcontroller. It displays 16
× 16-dot
characters and up to 12 lines of text with 24 characters per
line.
Features
Text structure: 12 lines
× 24 characters (Up to 288
characters)
Character format: 16
× 16 dots
Character display clock frequency: about 9 MHz
Character sizes: Four sizes each in the horizontal and
vertical directions with the size set in line units.
Number of characters supported: 512 (internal)
Up to 8192 using an external ROM (for Japanese)
[Reference]
JIS X0298 (1990): 6877 characters
JIS level 1 kanji: 2965 characters
JIS level 2 kanji: 3388 characters
Special characters: 524 characters
Display start positions: 128 positions each in the
horizontal and vertical directions
Blinking, reverse video, reversed blinking, and character
outlining: May be specified in individual character units.
Blinking types: Two types with periods of about 1.0 and
about 0.5 seconds.
Blanking: The whole font area (16
×16 dots) can be
blanked in line units
(Four types: no blanking, character size blanking,
character plus outlining size blanking, and whole area up
to adjacent character blanking)
Line spacing control: Zero to seven scan lines, in line
units
Character color: Eight colors in character units (in
internal synchronization mode): 2 fsc and 4 fsc
(Black, red, green, yellow, blue, magenta, cyan, and
white)
Character background color: Eight colors (in internal
synchronization mode): 2 fsc and 4 fsc
(Black, red, green, yellow, blue, magenta, cyan, and
transparent)
Screen background color: Eight colors (in internal
synchronization mode): 2 fsc and 4 fsc
(Black, red, green, yellow, blue, magenta, cyan, and
white)
External control inputs: Serial interface with an 8-bit
data size.
Built-in sync separator circuit
