LC78711E Overview
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. mm 3159-QFP64E [LC78711E].
