M65850 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 ponents and television sets. ◊ Increased master clock frequency assures high-performance short delay,enabling the IC to be used for dolby prologic surround system.
M65850 Key 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 undesi
- 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)
- Vcc=3.5~5.5V Rated supply voltage
- Vcc=5V
