Description

The M65850P/FP is a CMOS IC for generating echo to be added to the voice through a Karaoke microphone.

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

Increased 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 1 MHz) (Selection of delay time in a range between 15 ms and 200 ms)

• Small package (14-pin DIP: PRDP0014AA-A (14P4), 16-pin SOP: PRSP0016DE-A (16P2N-A))

• Built-in 20 Kbit SRAM

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

• Single power supply (5 V)
