Overview

The LC74776/M is an on-screen display controller CMOS

IC that displays characters and patterns on the TV screen

under microprocessor control. This IC includes a built-in

PDC/VPS/UDT interface circuit.

Functions

• Display format: 24 characters by 12 rows (Up to 288

characters)

• Character format: 12 (horizontal)

× 18 (vertical) dots

• Character sizes: Three sizes each in the horizontal and

vertical directions

• Characters in font: 256 (Of the 256 characters, one is a

space character (FE hexadecimal)

and one is a transparent space

character (FF hexadecimal))

• 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

• Blanking: Over the whole font (12

× 18 dots)

• Background color: 8 colors (internal synchronization

Blue background only: NTSC

• Line background color: Three lines can be set up.

8 line background colors (in

internal synchronization mode):

• External control input: 8-bit serial input format

• On-chip sync separator circuit

• Video outputs: PAL and NTSC format composite video

outputs

• Package: DIP30SD
