描述
ML226xx系列是内置有4Mbit~32Mbit Flash存储器的语音合成LSI。由于内置了大容量存储器,因此非常适用于语音操作指导等需要长时间播放语音的应用。此外,该系列产品还支持通过微控制器改写Flash存储器。产品采用实现高音质的HQ-ADPCM、16位D/A转换器和低通滤波器,并内置用来直接驱动扬声器的1.0W单声道扬声器放大器。语音输出所需的功能已经全部集成于1枚芯片中,因此仅需增加本LSI,即可轻松实现语音功能。

4- Channel Mixing Speech Synthesis LSI with Built-in Flash Memory  
Overview  
ML22Q663/ML22Q664/ML22Q665/ML22Q666 is a 4-channel mixing speech synthesis LSI with a flash memory for sound  
data. It is equipped with a I2C interface (slave).  
It adopts a HQ-ADPCM*1, 16-bit D/A converter, and low-pass filter for high sound quality, and incorporates a 1.0W mono  
speaker amplifier for driving speakers directly. It is also equipped with a function to detect failure.  
The functions necessary for sound output are integrated into a single chip, so that sound functions can be realized simply by  
adding this LSI.
