Description

BU8709KN is a melody sound source LSI for cellular

phones. This LSI generates 64 high quality polyphonic

tones through high sampling rate (fs=44.1KHz).

1 ADPCM encoder and 2 ADPCM decoders functions

are embedded, providing mixing capabilities. It can

customize output sounds by an equalizer function and

display the signals by Graphic Equalizer. It also has

Reverb function, as well as LED & Vib synchronization.
