R2A15906SP中文资料DIGITAL ECHO WITH MIC MIXING AMP数据手册Renesas规格书

描述 Description

The R2A15906SP is a CMOS IC that has a microphone peripheral circuit and an echo generation circuit for karaoke use, on a single chip.

特性 Features

・ High-performance digital echo circuit using 44-Kbit RAM
・ A mic amplifier with an ALC makes it possible to handle overload input, and the ALC operating voltage can be externally set to the desired value.
・ Built-in mic volume, echo volume, and feedback volume
・ Internal mic mixing amplifier
・ The clock has an internal current control-type oscillation circuit, and the generation of unnecessary oscillation can be prevented because the clock does not affect anything external to the unit.
・ Internal Auto Reset circuit that functions when the power supply is turned on.
・ MIC Volume, Echo Volume, and Feedback Volume are controlled by I2C Bus or DC control. (Delay Time is only I2C Bus )
・ 5 V single power supply
