KARAOKE

DESCRIPTION

àThe M65850P/FP is a CMOS IC for generating echo to be added to the voice through a "karaoke" microphone.

àIt is optimal to provide the echo effect function for karaoke player, such as radio cassette recorders, mini audio components and television sets.

àIncreased master clock frequency assures high-performance short delay,enabling the IC to be used for dolby prologic surround system.

FEATURES

•Built-in input/output filters, A-D and D-A converters,and memory realize a delay system with only a single chip.

•Built-in current control type clock oscillator circuit avoids clock affection outside,thus allowing prevention of undesired radiation.

•Delay time = 164 ms (with master clock set at 1MHz)

(Selection of delay time in a range between 15ms and 200ms)

•Small package (14-pin DIP : 14P4,16-pin SOP:16P2N)

•Built-in 20Kbit SRAM

•Built-in auto reset circuit (The IC reset as power is turned on)

•Single power supply (5V)
