Functional Description

Most of the microcontroller signals are routed to 0.1-in (2.54-mm) pitch headers. An internal multiplexer allows different peripheral functions to be assigned to each of these GPIO pads. When adding external circuitry, consider the additional load on the evaluation board power rails.

The LM4F120H5QR microcontroller is factory-programmed with a quickstart demo program. The quickstart program resides in on-chip Flash memory and runs each time power is applied, unless the quickstart application has been replaced with a user program.

2.1.2 USB Device

The Stellaris LaunchPad includes a USB micro-B connector to allow for USB 2.0 device operation. The signals shown in

Table 2-1

Power Management

2.2

Power Management

www.ti.com

2.2.1 Power Supplies

The Stellaris LaunchPad can be powered from one of two power sources:

• On-board Stellaris ICDI USB cable (Debug, Default)

• USB device cable (Device)

The POWER SELECT switch (SW3) is used to select one of the two power sources. Select only one source at a time.

2.2.2 Hibernate

The Stellaris LaunchPad provides an external 32.768-kHz crystal (Y1) as the clock source for the

LM4F120H5QR Hibernation module clock source. The current draw while in Hibernate mode can be measured by making some minor adjustments to the Stellaris LaunchPad. This procedure is explained in more detail later in this section.

The conditions that can generate a wake signal to the Hibernate module on the Stellaris LaunchPad are waking on a Real-time Clock (RTC) match and/or waking on assertion of the WAKE pin.

(1) The second user switch (SW2) is connected to the WAKE pin on the microcontroller. The WAKE pin, as well as the

V

DD and HIB pins, are easily accessible through breakout pads on the Stellaris LaunchPad. See the appended schematics for details.

There is no external battery source on the Stellaris LaunchPad Hibernation module, which means the

VDD3ON power control mechanism should be used. This mechanism uses internal switches to remove power from the Cortex-M4F processor as well as to most analog and digital functions while retaining I/O pin power.

To measure the Hibernation mode current or the Run mode current, the VDD jumper that connects the 3.3

V pin and the MCU_PWR pin must be removed. See the complete schematics (appended to this document) for details on these pins and component locations. An ammeter should then be placed between the 3.3 V pin and the MCU_PWR pin to measure I

DD

(or I

HIB_VDD3ON

). The LM4F120H5QR microcontroller uses V

DD as its power source during V

DD3ON

Hibernation mode, so I

DD is the Hibernation mode (VDD3ON mode) current. This measurement can also be taken during Run mode, which measures

I

DD the microcontroller running current.

2.2.3 Clocking

The Stellaris LaunchPad uses a 16.0-MHz crystal (Y2) to complete the LM4F120H5QR microcontroller main internal clock circuit. An internal PLL, configured in software, multiples this clock to higher frequencies for core and peripheral timing.

The Hibernation module is clocked from an external 32.768-KHz crystal (Y1).

2.2.4 Reset

(1)

The RESET signal into the LM4F120H5QR microcontroller connects to the RESET switch and to the

Stellaris ICDI circuit for a debugger-controlled reset.

External reset is asserted (active low) under any of three conditions:

• Power-on reset (filtered by an R-C network)

• RESET switch held down

• By the Stellaris ICDI circuit when instructed by the debugger (this capability is optional, and may not be supported by all debuggers) spacer spacer

If the board does not turn on when you connect it to a power source, the microcontroller might be in Hibernate mode (depending on the programmed application). You must satisfy one of the programmed wake conditions and connect the power to bring the microcontroller out of Hibernate mode and turn on the board.

Programming the Stellaris LaunchPad Evaluation Board

3.4

Programming the Stellaris LaunchPad Evaluation Board

The Stellaris LaunchPad software package includes pre-built binaries for each of the example applications. If you have installed StellarisWare to the default installation path of C:\StellarisWare, you can find the example applications in C:\StellarisWare\boards\ek-lm4f120xl. The on-board Stellaris ICDI is used with the Stellaris LM Flash Programmer tool to program applications on the Stellaris LaunchPad.

Follow these steps to program example applications into the Stellaris LaunchPad evaluation board using the Stellaris ICDI:

1. Install LM Flash Programmer on a PC running Microsoft

®

Windows

®

.

2. Switch the POWER SELECT switch to the right for Debug mode.

3. Connect the USB-A cable plug to an available port on the PC and the Micro-B plug to the Debug USB port on the board.

4. Verify that the POWER LED D4 on the board is lit.

5. Run the LM Flash Programmer.

6. In the Configuration tab, use the Quick Set control to select the EK-LM4F120XL evaluation board.

7. Move to the Program tab and click the Browse button. Navigate to the example applications directory

(the default location is C:\StellarisWare\boards\ek-lm4f120xl\).

8. Each example application has its own directory. Navigate to the example directory that you want to load and then into the directory which contains the binary (*.bin) files. Select the binary file and click

Open.

9. Set the Erase Method to Erase Necessary Pages, check the Verify After Program box, and check

Reset MCU After Program.

Program execution starts once the Verify process is complete.

EVALUATION BOARD/KIT/MODULE (EVM)

WARNINGS, RESTRICTIONS AND DISCLAIMERS

For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this EVM is not a finished electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end product.

Your Sole Responsibility and Risk. You acknowledge, represent and agree that:

1.

You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug

Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.

2.

You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard.

3.

Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards (such as UL,

CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items.
