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.

Serial Data Input Timing
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
