IntroductionandDescription

TheTexasInstrumentsTRF7960evaluationmodule(EVM)helpsdesignersevaluatetheperformanceof theTRF7960multiple-protocolRFIDtransceiver.
ThismanualincludesalistofEVMfeatures,abriefdescriptionofthemodule,EVMspecifications,details onconnectingandusingtheEVM,andadiscussionofthesoftwareinterfacefortheEVM.TheEVMis usedtodemonstratethecapabilitiesofthedevice(32pinQFN)andhelpaidtheuserinthedevelopment process.Thedeviceincorporatesananalogfrontend,protocolhandling,framing,errorchecking,and multipleintegratedvoltageregulatorswithotherfeaturesthatallowthereadertobe customized/configurablefortheendapplication.

1.1Description

TheTRF7960EVMfeaturesinclude:
•SupportfortheISO15693standard
•SupportforboththeISO14443AstandardandtheISO14443Bstandard(uptolayer4)
•SupportfortheTexasInstrumentsTag-it™standard
•Selfcontained–hasanon-board13.56-MHzloopantennaandinterface
•CommunicationwithhostsoftwareonaWindows-basedPCthroughastandardUSBcable
•ProtocolindicationLEDs–(standalonemode)requiredtoindicatedetectionofatag.
TheTRF7960EVMRev.Ahasthefollowingadditionalhardwarefeatures:
•SupportsbothPARALLELandSPIcommunicationinterfacesbetweentheTRF7960andtheMSP430 on-board(configurableusinganon-boardjumpersetting)
•Afasterandlower-powerMSP430onboard.TheTRF7960EVM(Rev.A,Figure2-2)usesthe state-of-theartMSP430F2370withmaximumspeedsupto16MHzandisavailableinatiny40-pin QFNpackage.
•Power-selectionjumper
Note:Thepower-selectionjumperisusedtoconnectthe5VcomingfromtheUSBbustoVINof
theRFIDreaderchip.Bydefault,whentheEVMsareshipped,thisjumperisconnectedso thatwhentheEVMispluggedintotheUSBportofaPC,theTRF7960andtheallthe associatedcircuitsarepowered.
