4-channel mixing speech synthesis LSI with a flash memory for sound data. It is equipped with an I2C interface. 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.
