A.IntroductionofSTM32
STM32isbasedonthefamilyofARMCortex-M3core-designedspecificallyforembeddedapplicationsthatrequirehighperformance,lowcost,lowpowerconsumption.Theperformanceisdividedintotwodifferentseries:
STM32F103the"Enhanced"seriesandSTM32F101the"Basic"series.TheclockfrequencyofEnhancedSeriesisupto72MHz,thehighestperformanceofsimilarproducts;theclockfrequencyofBasicSeriesis36MHz,andthepricesof16positionproductssignificantlyenhancetheperformanceofmorethan16positionproducts,isthebestchoiceuserstobuythem.Thetwoseriesarebuilt-inflashfrom32Kto128K,isthecombinationofthemaximumcapacityoftheSRAMandperipheralinterfaces.Whentheclockfrequencyreaches72MHz,itexecutesfromFlashandtheSTM32powerconsumptionis36mA,thelowestpowerconsumptioninthe32-bitmarketproducts,theequivalentanimpressive0.5mA/MHz.
