The BU8768FV is a tone generator IC for cellular
phones that can produce triple chords simultaneously.
Tone and volume in each sound source can be controlled
separately by serial control. Master volume is integrated.
Output can be selected from pseudo sine wave and
special square wave. The special square wave is a
waveform that can take sound pressure by even a small
speaker.
1) Three chords are generated by CPU control.
2) Master clock (4.8MHz/3.25MHz)
3) Adjustable parameter needed for generating chords.
4) Built-in DTMF generating function
5) Can select a waveform parameter for generating sound.
6) Control from CPU by serial data
7) Built-in LPF for smoothing
8) SSOP-B16 package
Melody sound at receiving or holding a call.
