CMOS LSI
LC78711E
Graphics Display Processor
Overview
The LC78711E is a CMOS LSI that provides graphics
display drawing functions. In addition to implementing
graphics display for NTSC and PAL signals, it provides
two 32 × 32-dot sprite display patterns and can easily
implement a wide range of displays.
Features
• Two-chip structure consisting of this LSI, the
LC78711E, and an external 64-K × 4-bit RAM. (An
RGB encoder is built in.)
• Graphics drawing controlled by a microprocessor over a
serial interface.
• Includes two crystal oscillator systems, one for NTSC
and one for PAL, and these system can be easily
switched using the provided control pin.
The standard clocks and all necessary internal timings
can be generated by connecting two crystals, a
14.31818-MHz crystal for NTSC, and a 17.734476-MHz
crystal for PAL.
• Two 32 × 32-dot sprite patterns provided. Up to two
sprites can be displayed, either two different types or the
same pattern in two different locations.
• 16 colors from a palette of 4096 colors can be displayed
in graphics screens, and seven colors can be displayed in
sprite patterns.
• Y/C signal outputs (two 8-bit D/A converter outputs)
• Supports the superimpose function, and provides a
timing signal output.
• Provides a color bar signal output function.
• Adopts an 8-bit serial data input format for the external
control input.
