LC74780, LC74780M

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, T aito-ku, TOKYO, 110-8534 JAPAN

Overview

The LC74780 and LC74780M are CMOS, video display
controllers for superimposing text and low-level graphics
onto an NTSC, PAL or PAL-M compatible television re­ceiver. Up to 288, 12 × 18-pixel characters can be displayed
under microprocessor control on a 24-character by 12-line
display.
The LC74780 and LC74780M feature selectable pixel width
and height, and 64 vertical and 64 horizontal display start
positions. It also features a flashing enable bit for each char­acter position.
The LC74780 and LC74780M operate from a 5V supply.
The LC74780 is available in 24-pin DIPs, and the
LC74780M, in 24-pin MFPs.

Features

• Complete text and graphics vide overlay circuitry.

• 128-character internal character generator ROM.

• 12 × 18-pixel characters.

• Three pixel widths and three pixel heights.

• Selectable background color.

• 8 colors at 4f

• 4 colors at 2fSC (NTSC)

• Built-in synchronization check and separation circuitry.

• Approximately 0.5 or 1 s period character flashing op­tion.

• Screen blanking.

• NTSC, PAL and PAL-M format compatibility.

• 8-bit serial input format.

• 5V supply.

• 24-pin plastic DIP and 24-pin plastic MFP.

Display Control Features and Characteristics

Display Control Command Structure

The display control commands, COMMAND0 to COM­MAND7, are shifted in 8-bit serial units. The first byte of a
command consists of an identification code and data. The
second byte consists of data only . Once the command iden­tification code in byte 1 has been written, it is saved until
