Melody LSI for Cellular Phone
BU8763FV
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 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.
!Applications
Melody sound at receiving or holding a call
!Features 1) Generating 3 waves, Controlled by CPU 2) Selectable master clock (5.376MHz / 2.688MHz) 3) Changeable parameter for wave generate 4) Including DTMF create function 5) Changeable Sine wave or special square wave 6) Serial control from CPU 7) Include smoothing filter (fc=20KHz) 8) SSOP-B16 package

!Note for use 1) WAVE1, WAVE2, WAVE3 register, ATT123 register (at melody output), ATT register, ENVON register are changed when output is a zero cross. 2) FREQ [5:0] register is changed instantaneously. 3) In the case that unsound part is set up WAVE 1,2,3 register, wave is stopped with a zero cross. when it changes FREQ[5:0] before becoming off with a zero cross, new frequency wave output one cycle. After wait for to do off with a zero cross, change FREQ[5:0]. 4) 3 sound resources can only the setting of all sine wave or all special square wave. 5) 3 sound resources can only the setting of all DTMF/TONE or all MELODY. 6) A data value of registration etc. is held at the time of SLEEP. 7) At the time of RESET, a data value of registration etc. becomes initial value. 8) Maximum output level (ATT=0dB) of one sound resource is 342.5mVrms (typ). Set up each ATT123 sol that output levels of totals 3 sound resources does not exceed, because a maximum output level of DAC is 2.00VPP (707.1mVrms). 9) TNSEL of address 0 D4 is a setting register about whether output which of DTMF or MELODY. 10) FSEL of address 0 D3 is a setting register about whether make the setting of FREQ etc. which of DTMF or MELODY.
