Description

BU8763FV is a melody LSI 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.

Master clock can be selected from 5.376MHz or 2.688MHz. Output of BU8763FV can be changed sine wave or special square wave.

The special square wave is a waveform that can take sound pressure by even a small speaker.
