4-channel mixing speech synthesis LSI with a serial audio interface and a serial flash memory interface for sound data. It adopts a HQ-ADPCM*1, 16bit 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.
