Refer to the voltage during PLAY with DASC OFF(atthe normal speed) unless otherwise specified; The value shownin ( ) is the voltage measured at the moment of STOP.363534202122A8A9NRASNRESETZSENSEVDD3332313029282726252423NWED1D0D3D2NCASA10YMCLKYMDATAYMLDYDMUTE1413121110987654321495051525354555657585960SQCKBLKCKTLOCKFLOCKSENSEMLDMDATAMCLKTXDVSS1DVDD1SRDATALRCKBCLKDSLF2AVDD2AVSS2EFMPCKCK176SUBCSBCKVSSX1X2VDD8079787776757473727170696867666564636261SSELMSELPSELFSELRSELOUTRAVSS1OUTLAVDD1TESTARSTFLAG6RESYCRCCLVSFLAGIPFLAGFCLKCLDCKTRVSTP220u6.3+R182AR201A1100u6.3+R301AC1661K1KC171C172A2.2KR183A473213863646530622827807978C177A1636913MHz16.9344C167A20P39PC168AX1R47A 10C169A 110+2.8V+2.8V0.022C305560KR307AR306A15K47KR202AC202C302R302A47K4.7u50+C303C301C2014.7u50+C20315KR206A-+R204A-+VR101B50K300PR320A 3KC304R304A470C3204.7u50+47u1087100KR303A470VR101A300PR220A 3K50K+4.7u506+5C22047u10C204R203A100K+C184470u101C306+220u6.3560KR207AC2050.022R309A10R322A4.7K10R49A220u6.3243C206+R209A10+2.8V4.7u50+4.7KR42AC8R311A680R222A4.7K10KR55AR41A4.7KR211A680100KR69A100R310A0.22C307A100R210AC207A0.22C3211000P1000PC221R321A470470R221ALGRRLGC3224.7u50+89712484745272829303132334443A8VCC13A11012A311A2A09A51514A418A61716A7GNDD16783NRAS45NWED012VCCD221201924GND2322NCASD32625363534A10GNDA9NCNCNC313027324142434429283536373839403334NCNCASD2D3GNDA8A5A4A6A7GND1331D0D12132333442434441NCNCNRASA9NWE54376VCC89A0A211A31210A114302526362829222324202137384039191617181535NCNCNC22Ou6.3+1.5K+22u1622Ou6.3C145L10533uH1100325432L106 95uHC147A47P1R138A10C1460.01R134AC148C150100u16+32+5.5VR137A+2.8V+5.5VC144C933KR61AR59A33K15KR57A10KR58A395122KR54A22KR56A11+4.8V+4.8V+5.5V+5.5V+5.5V4.7KR48A330R30A1.2KR31AR32A1.5KR33A1.8KR34A2.4KR35A3.6KR38AR76A3.3K10KR75A47KR68A13210R46A+2.6V+2.6V+2.8V+2.8V+2.8V+2.7V52+2.2V+2.2V+2.2V+2.2V+2.2V+2.2V+2.2VC182A1R43A10K10KR66A2700P2700P+2.8V+2.8V+2.8V+2.7V+2.7V+2.7V+2.8V+2.8V+2.7VC6A0.1+2.8V+2.8V16202117526.8KR29A22231C5A+2.8V+2.8V+2.8V+2.8V+2.8V+2.8V+2.8V+5.5V+5.5V+5.5VQ205,305DIGITAL LINEGND LINESIGNAL LINE+BR40A +B+B+B+B330R139A10KR87A1KR86A100u6.3C153+100R646010KR88A10KR89A3.9R85A4.7R84AR83A 1KJP15A22KR77A47KR78A1.5KR52A10KR50A1.2KR51AEUROPEE9NOU.K.DESTINATIONCOUNTRYAUSTRALIAABB.X9T9JP11A,13A,15AR50A,YESYES75A-78AASM5902AFIC5IC6YESNOIC7YESR51A,52ANOYESQ113D119,120YESR50A,JP11A,DESTINATIONSM5859AFGENERAL MARKETCOUNTRYNOYESAM3ABB.13ANOIC6IC577A,78AAUSTRALIAX3CANADAP3EUROPEE3M4GENERAL MARKETNO52AR51A,JP15AYESNOQ114NOYESR50A,77A,78AE7EUROPESM5902AFGENERAL MARKETDESTINATIONU.K.CANADACOUNTRYM7T7P7ABB.NOAIC5YES76AR75A,JP11A,13A,15AYES1C162AC183A1000P6.8KR74ANO52AR51A,100NOYESQ114IC7YESQ113YESNONOYESNOYESD119,120YESNONOYESNOYESNOYESR75ANOYESYESYESIC6IC7NONOYESYESQ113Q114D
