Overview
Ordering number : EN5476 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.
Package Dimensions unit: mm 3159-QFP64E [LC78711E] 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.
