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. 0. 20 Description Limits Symbol Supply voltage range VDD Power dissipation Pd –0.3 ~ +4.5 450 ∗ Operating temperature range Topr –40 Storage temperature range Tstg –50 ~ +85 ~ +125 Unit V mW ˚C ˚C ∗Derating : 4.5mW/˚C for operation above Ta=25˚C February, 2003 Recommended Operating Conditions (Ta=25˚C) Parameter Symbol Min.
