BU8788KN General Description

BU8788KN is a melody sound source LSI for cellular phones. This LSI generates 32 polyphonic tones simultaneously and is capable of generating user's own sounds by an ADPCM decoder. A total of 207 tones(128tones+47drums +32effect sounds) can be generated. FIFO and Sequencer for playing are incorporated. The sequencer itself can control the timing and play the music by sending the melody data to FIFO.
