SPMU296 –April2013 Hardware Description The TivaC SeriesLaunchPad includesa TM4C123GH6PM microcontrollerand an integratedICDIas well as a range of usefulperipheralfeatures(as the blockdiagram in Figure2-1 shows).This chapter describeshow theseperipheralsoperateand interfacetothemicrocontroller. Figure2-1.TivaC SeriesLaunchPad EvaluationBoard Block Diagram

2.1 FunctionalDescription

2.1.1 Microcontroller

The TM4C123GH6PM isa 32-bitARM Cortex-M4-basedmicrocontrollerwith256-kBFlashmemory, 32- kB SRAM, and 80-MHz operation;USB host,device,and OTG connectivity;a Hibernationmodule and PWM; and a widerangeofotherperipherals.See theTM4C123GH6PM microcontrollerdatasheet (literaturenumber SPMS376 )forcompletedevicedetails. 7SPMU296 –April2013 Hardware Description SubmitDocumentationFeedback Copyright© 2013,Texas InstrumentsIncorporated

The TM4C123GH6PM microcontrollerisfactory-programmedwitha quickstartdemo program.The quickstartprogramresidesinon-chipFlashmemory and runseach timepower isapplied,unlessthe quickstartapplicationhas been replacedwitha userprogram.

2.1.2 USB Connectivity

The EK-TM4C123GXL isdesignedand functionsas a USB devicewithouthardwaremodification.The USB devicesignalsarededicatedtoUSB functionalityand arenotsharedwiththeBoosterPackheaders. The USB devicesignalsarelistedinTable2-1. Table2-1.USB Device Signals GPIO Pin Pin Function USB Device PD4 USB0DM D – PD5 USB0DP D+ The TM4C123GH6PM targetdeviceisalsocapableofUSB embedded hostand on-the-go(OTG) functions.OTG functionalitycan be enabledby populatingR25 and R29 with0-Ω resistors.These resistorsconnecttheUSB ID and USB VBUS signalstoPB0 and PB1. When theseresistorsarepopulated, PB0 and PB1 must remainintherespectiveUSB pinmode configurationstopreventdevicedamage. PB0 and PB1 arealsopresenton theJ1 BoosterPackheader.Therefore,ifR25 orR29 arepopulated,care must be takennottoconflictthesesignalswithBoosterPacksignals. USB embedded hostoperationcan be enabledinthesame way forUSB devicesthatareself-powered. Providingpower when actingas a USB hostrequiresa BoosterPackwithpower switchingand appropriate connectors.AllUSB hostsignalsareavailableon theBoosterPackinterfaceexceptD+ and D –,whichare onlyavailableon theUSB micro-A/-Bconnectorand thetwo adjacenttestpoints. When connectedas a USB device,theevaluationboardcan be powered fromeithertheICDIortheUSB Deviceconnectors.The usercan selectthepower sourceby moving thePOWER SELECT switch(SW3) totheDeviceposition.See thePower Management schematic(appendedtothisdocument).

2.1.3 Motion Control

2.2 Power Management

2.2.1 Power Supplies

The TivaC SeriesLaunchPad can be powered fromone oftwo power sources:

On-boardICDIUSB cable(Debug,Default)
USB devicecable(Device) The POWER SELECT switch(SW3) isused toselectone ofthetwo power sources.Selectonlyone sourceata time.

2.2.2 Hibernate

The TivaC SeriesLaunchPad providesan external32.768-kHzcrystal(Y1)as theclocksourceforthe TM4C123GH6PM Hibernationmodule clocksource.The currentdraw whileinHibernatemode can be measured by making some minoradjustmentstotheTivaC SeriesLaunchPad.Thisprocedureis explainedinmore detaillaterinthissection. The conditionsthatcan generatea wake signaltotheHibernatemodule on theTivaC SeriesLaunchPad arewakingon a Real-timeClock(RTC) match and/orwakingon assertionoftheWAKE pin.(1) The second userswitch(SW2) isconnectedtotheWAKE pinon themicrocontroller.The WAKE pin,as wellas the VDD and HIB pins,areeasilyaccessiblethroughbreakoutpads on theTivaC SeriesLaunchPad.See the appended schematicsfordetails. spacer spacer spacer spacer (1) Iftheboarddoes notturnon when you connectittoa power source,themicrocontrollermightbe inHibernatemode (dependingon the programmed application).You must satisfyone oftheprogrammed wake conditionsand connectthepower tobringthemicrocontroller outofHibernatemode and turnon theboard. 11SPMU296 –April2013 Hardware Description SubmitDocumentationFeedback Copyright© 2013,Texas InstrumentsIncorporated

In-CircuitDebug Interface(ICDI) www.ti.com Thereisno externalbatterysourceon theTivaC SeriesLaunchPad Hibernationmodule,whichmeans theVDD3ON power controlmechanism shouldbe used.Thismechanism uses internalswitchesto remove power fromtheCortex-M4processoras wellas tomost analogand digitalfunctionswhile retainingI/Opinpower. To measure theHibernationmode currentortheRun mode current,theVDD jumperthatconnectsthe3.3 V pinand theMCU_PWR pinmust be removed.See thecompleteschematics(appendedtothis document)fordetailson thesepinsand component locations.An ammeter shouldthenbe placed between the3.3V pinand theMCU_PWR pintomeasure IDD (orIHIB_VDD3ON ).The TM4C123GH6PM microcontrolleruses VDD as itspower sourceduringVDD3ON Hibernationmode, so IDD istheHibernation mode (VDD3ON mode) current.Thismeasurement can alsobe takenduringRun mode, whichmeasures IDD themicrocontrollerrunningcurrent.

2.2.3 Clocking

The TivaC SeriesLaunchPad uses a 16.0-MHz crystal(Y2)tocompletetheTM4C123GH6PM microcontrollermain internalclockcircuit.An internalPLL,configuredinsoftware,multiplesthisclockto higherfrequenciesforcoreand peripheraltiming. The Hibernationmodule isclockedfroman external32.768-KHzcrystal(Y1).

2.2.4 Reset

The RESET signalintotheTM4C123GH6PM microcontrollerconnectstotheRESET switchand tothe ICDIcircuitfora debugger-controlledreset. Externalresetisasserted(activelow)underany ofthreeconditions:

2.3 In-CircuitDebug Interface(ICDI)

The TivaC SeriesLaunchPad evaluationboardcomes withan on-boardIn-CircuitDebug Interface(ICDI). The ICDIallowsfortheprogrammingand debug oftheTM4C123GH6PM usingtheLM FlashProgrammer and/orany ofthesupportedtoolchains.Note thattheICDIsupportsonlyJTAG debugging.An external debug interfacecan be connectedforSerialWireDebug (SWD) and SWO (trace).
