1.1.PowerManagement

Eight low-dropoutregulatorsdesignedspecificallyforGSMapplicationspowertheterminaland helpensureoptimal

systemperformance and long batterylife.Aprogrammableboostconverterprovides supportfor1.8V,3.0VSIMs,

whileaself-resetting,electronicallyfusedswitchsuppliespowertoexternalaccessories.Ancillarysupportfunctions,

suchasRTCmodule and High VoltageChargepump,Clock generator,aidinreducing both boardarea and system

complexity.

I2C BUSserial interface providesaccess tocontroland configuration registers.Thisinterface givesamicroprocessor

full controlofthePCF50603 and enables systemdesignerstomaximize bothstandby and talktimes.

Supervisoryfunctions.including aresetgenerator,aninputvoltagemonitor,and atemperaturesensor,supportreliable
