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.
