M65850FP中文资料DIGITAL ECHO(DIGITAL DELAY)数据手册MITSUBISHI规格书

描述 Description

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 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)
