50^SERIES
KARAOKE
SINGLE CHIP KARAOKE PROCESSOR
DESCRIPTION
*The M65851FP is an LSI that not only contains circuits (echo and key control) necessary for Karaoke but also improves
other peripheral functions.
*This IC has full peripheral functions including vocal cut, phase shifter, equalizer,detection of intervals between songs,
digital surround, and Karaoke scoring. It is therefore suitable not only for dedicated Karaoke units but also for radio
cassette tape recorders, TV,VCR,and miniature unit audio systems with Karaoke function.
FEATURES
*Capable of composing echo and key control circuits necessary for Karaoke system
for Karaoke system with a single chip
*Echo circuit is capable of supporting digital surround by adopting 16Kbit RAM
built-in digital delay
*17steps of -8 to +8 for key control (1step is equivalent to a half tone)
*Karaoke entertainment functions such as Karaoke scoring,vocal cut, equalizer,
phase shifter, detection of intervals between songs, and magic voice functions
*Generation of unnecessary radiation is avoided because clock's built-in
current-control oscillation circuit keeps clock effects inside the clock
*Built-in automatic reset circuit activated with power turned on
*5V single power supply
