LC74711

Controller LSI for On-screen Displays

Preliminary

Overview

The LC74711 is a CMOS LSI for applications involving

microcomputer control of on-screen character and

graphics displays. Built-in character ROM supplies 128

alphanumerics and each character is generated in a 12

by 18 pixel format. The display is capable of supporting

a maximum of 288 characters within a 24 characters by

12 line array.

Functions and Applications

(1) Screen construction:

24 characters X 12 lines

(2) Number of characters displayed:

Maximum 288 characters capacity

(3) Display control ROM (line ROM):

64 lines (line unit control: 24 character construction)

(4) Display RAM:

176 characters (supporting extended character

selection)

(5) Character construction: 12 (horizontal) X 18

(vertical) pixels

(6) Character set: 128 types of characters

(7) Character size:

4 horizontal types and 4 vertical types

(8) Display starting position: 64 types horizontally and

64 types vertically

(9) Blinking: Character units

(10) Blinking types: 2 types with approximate 1.0 s and

0.5 s cycles and 3-type selection for 25%, 50% and

75% duty

(11) Blanking: Font complete blanking (12 X 18 pixels)

(12) Background color: 8 background tints (during

internal synchronizing operation: 4 fsc when using

crystal oscillator)

(13) External control input: Serial data input

(14) Synchronizing signal: Internal synchronizing,

supports external synchronizing changeover

(15) Built-in synchronizing separator circuit

(16) Video output: NTSC system composite video

output

(17) Superimpose: Characters superimposed over

composite video output

(18) Package: DIP-22S
