BU8763FV Communications 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 !Absolute maximum ratings (Ta=25°C) Parameter Symbol Limits Unit Digital supply voltage DVDD −0.3 to +4.5 V Analog supply voltage AVDD −0.3 to +4.5 V Input voltage for digital VDIN DVSS−0.3 to DVDD+0.3 V Input voltage for analog VAIN AVSS−0.3 to AVDD+0.3 V mW Pd 450∗ Storage temperature range Tstg −50 to +125 °C Operating temperature range Topr −20 to +70 °C Power dissipation + ∗ To use at temperature higher than 25 C, derate 4mW / C, PCB(70mm 70mm, d=1.6mm glass epoxy) 1/11 BU8763FV Communications DGND TEST1 TEST2 TEST3 TEST4 AVDD AGND 15 14 13 12 11 10 9 16 9 DVDD 16 !Block diagram TEST CIRCUIT WAVEFORM GENERATOR WAVE GEN 1(h) ATT 1 WAVE GEN 2(m) ATT 2 WAVE GEN 3(l) ATT 3 ATT SMOOTHING FILTER DAC 1 1 2 3 4 5 6 7 8 CKSEL SCLK SDATA SSTB RSTB TEST5 AOUT CONTROL REGISTER MCLK CLOCK GENERATOR + 8 2/11 BU8763FV Communications !Pin list Pin No. Pin name Functions I/O Type Circuit 1 MCLK Master clock input I CMOS A 2 CKSEL Master clock select I CMOS A 3 SCLK Serial clock input I CMOS A 4 SDATA Serial data input I CMOS A Others Hi : 2.688MHz, Lo : 5.376MHz 5 SSTB Serial strobe input I CMOS A 6 RSTB Reset input I CMOS A Lo : Reset 7 TEST5 test pin O Analog C Do not connect 8 AOUT Melody output pin O Analog C 9 AGND Analog ground PWR 10 AVDD Analog power supply PWR 11 TEST4 test pin O CMOS B Do not connect 12 TEST3 test pin I CMOS A Please connect to ground 13 TEST2 test pin I CMOS A Please connect to ground 14 TEST1 test pin I CMOS A Please connect to ground 15 DGND Digital ground PWR 16 DVDD Digital power supply PWR PAD A PAD Input Buffer B Output Buffer (Digital) PAD C Output Buffer (Analog) 3/11 BU8763FV Communications !Electrical characteristics Digital characteristics (Unless otherwise noted DVDD=AVDD=3.0V, Ta=25°C) Parameter Conditions Symbol Min.
