Overview
The LC74751 is a CMOS LSI that supports on-screen
display of characters and patterns on a TV screen under
the control of a microcontroller. The LC74751 includes an
on-chip character ROM that provides 128 characters in a
12
× 18 dot format. This IC supports display of up to 12
lines of 24 characters each for a maximum of 288
characters.
Features
Display format: 24 characters by 12 rows
Characters displayed: Up to 288 characters
Display control ROM (line ROM): ROM for 64 lines
(Control in line units: lines consisting of 24 characters)
Display RAM: 176 characters (Used for the specification
of user-defined characters.)
Character format: 12 (horizontal)
× 18 (vertical) dots
Characters in font: 128
Character sizes: Four sizes each in the horizontal and
vertical directions
Initial display positions: 64 horizontal positions and 64
vertical positions
Blinking: Specifiable in character units
Blinking types:
— Two periods supported: 1.0 second and 0.5 second
— Three duty types supported: 25%, 50%, and 75%
Blanking: Over the whole font (12
× 18 dots)
Background color
—8 background colors (in internal synchronization
mode): 4fsc (NTSC/PAL/PAL-M/PAL-N)
—4 background colors (in internal synchronization
mode): 2fsc (NTSC)
— Single background color (blue) (in internal
synchronization mode): 2fsc (PAL/PAL-M/PAL-N)
External control input: Serial data input
Synchronizing signals: Supports switching between
internal and external synchronizing signals.
On-chip sync separator circuit
Video output: Composite video output in the NTSC,
PAL, PAL-M, or PAL-N format
Superimpose function: Superimposes the character
output on the composite video output.
