Stellaris® LaunchPad and BoosterPack Expansion
Concept and Overview
The Texas Instruments’ Stellaris® LM4F120 LaunchPad concept is an extremely low-cost, expandable evaluation system for TI microcontrollers. This concept began with the tremendously successful MSP430™ LaunchPad which introduced a large number of engineers to the TI
MSP430 family of microcontrollers. The TI Stellaris microcontroller family is expanding on that success by introducing the Stellaris® LM4F120 LaunchPad featuring the Stellaris ARM®
Cortex™-M4F LM4F120H5QRFIG microcontroller.
A Stellaris LaunchPad consists of a target microcontroller, an in-circuit debug interface (ICDI) such as JTAG, a regulated power supply, a minimal microcontroller support circuit, a user interface, and a set of expansion headers. The expansion headers are referred to as the BoosterPack interface.
A BoosterPack is an expansion card designed for this interface. This interface provides a mechanism for developers to easily extend the Stellaris LaunchPad with application- and user-specific functions.
The Stellaris LaunchPad provides a BoosterPack interface that is compatible with the MSP430
LaunchPad. In addition, the Stellaris LaunchPad provides access to additional Stellaris functionality through an extended BoosterPack interface called the BoosterPack XL Interface.
BoosterPack interfaces with highly similar functionality for expansion will be available for the
Stellaris LaunchPad, in addition to microcontroller-family-specific functionality available on a
BoosterPack XL Interface for additional options. Table 1-1 provides a summary of BoosterPack
interface compatibility.

BoosterPack Functional Interface
The Stellaris® LaunchPad's BoosterPack Interface provides compatibility with the original
MSP430 LaunchPad's BoosterPack interface. This interface consists of the outer 10 pin headers.
The pins are spaced 0.10-inch apart with the two headers located 1.8 inches apart.
Table 1-2, ”J1Connector” on page 8 and Table 1-3, ”J2 Connector” on page 8 provide information
for which Stellaris microcontroller peripherals are routed to each of the interface pins. The J1 connector is located on the far left side of the Stellaris LaunchPad. The J2 connector is located on the far right side of the Stellaris LaunchPad. Software is used to configure the LM4F120 pin for one of the functions found in the table. Highlighted functions indicate configuration for compatibility with the MSP430 LaunchPad.

Stellaris LaunchPad BoosterPack Development Guide
BoosterPack XL Functional Interface
The BoosterPack XL Interface consists of the J1 and J2 connectors as well as the inner 10-pin headers spaced 1.6 inches apart directly inside of the MSP430 LaunchPad-compatible
BoosterPack interface headers. The pins are spaced on 0.10-inch centers. These inner 10-pin headers (connectors J3 and J4) are not intended to be compatible with other TI LaunchPads or
LaunchPad XL's. This is a Stellaris-only interface. TI recommends that LaunchPads provide analog functions on the left side of the BoosterPack XL interface and timer or PWM functions on the right side of the BoosterPack XL interface. Stellaris conforms to these recommendations. No effort has been made to make this interface compatible with any other LaunchPad.
Table 1-4 and Table 1-5 show which Stellaris peripherals are routed to each pin of the
Stellaris-only BoosterPack XL Interface pins. J3 is the inner left BoosterPack XL Interface header.
J4 is the inner right BoosterPack XL Interface header. Software is used to configure the LMF4120 pin for one of the functions found in the table.

LaunchPad Power Interface
The Stellaris LaunchPad has provisions to provide power to a BoosterPack through either the
BoosterPack interface or the BoosterPack XL Interface. The configuration of power and ground pins on both of these interfaces must be consistent across LaunchPads from all TI microcontroller families.
The Stellaris LaunchPad draws power from either of the on-board USB interfaces as selected by the power switch in the top left corner of the board. Typically, the USB connection provides
500 milliamps at 5 V to the Stellaris LaunchPad. The selected USB power source is made directly available to the BoosterPack XL Interface on the J3.01 pin. This is a direct connection with only small decoupling capacitors provided on the Stellaris LaunchPad.
All LaunchPads, including the Stellaris LaunchPad, also provide a 3.3-V supply on pin J1.01 of the
BoosterPack interface. On the Stellaris LaunchPad, this is sourced by a TPS73633 LDO voltage regulator which converts the selected 5-V USB power to 3.3 V. The regulator is capable of sourcing 400 milliamps at 3.3 V. This 3.3-V supply is shared between the BoosterPack interface, the in-circuit debug interface (ICDI), and the target microcontroller. Therefore, under normal circumstances, about 300 to 350 milliamps are available to the BoosterPack interface. Detailed power management is left to the BoosterPack developer who must also manage the application to be run on the target microcontroller.
The Stellaris LaunchPad can be powered through an external supply on a BoosterPack. If providing power to the Stellaris LaunchPad from a BoosterPack, move the power select switch to select an unused USB connection to prevent power bus contention between the BoosterPack and the USB connection. Power may be supplied to either the 3.3 V or the 5.0-V system but not both.
Providing external power to both 5 V and 3.3 V would result in a contention between the external power supplies and the Stellaris LaunchPad's voltage regulator. Providing only 3.3 V will result in some lost functionality such as the on-board LED’s. It may also result in reverse current leakage through the on-board voltage regulator. Therefore, it is recommended if providing power externally to use either the existing USB connections or an external 5-V supply from a BoosterPack.
Ground connections are available on pins J2.01 and J3.02. These provide a ground connection for both the BoosterPack interface and the BoosterPack XL Interface respectively.
Additional power and ground pins are available through labeled pins located in the extreme lower corners of the Stellaris LaunchPad. These are connected to the same 3.3 V, 5 V, and ground connections as the pins on the BoosterPack interface and the BoosterPack XL Interface.

Stellaris LaunchPad BoosterPack Development Guide
Special Consideration for Shared Pins
To provide compatibility with the MSP430 LaunchPad's BoosterPack interface and to provide a maximum number of signals to the BoosterPack interface and BoosterPack XL Interface, it was necessary to route some signals to more than one pin. In addition, certain on-board functions such as the button and LED signals are available on the BoosterPack interface and BoosterPack XL
Interface. A 0-
Ω jumper resistor was installed for signals that are used for more than one purpose or routed to more than one GPIO. Removal of this jumper disconnects the functions. All jumpers
are installed by default. A listing of these jumpers and their use is provided in Table 1-6.

Stellaris LaunchPad Dimensions and Mating
Figure 1-1 on page 7 shows a dimensional drawing of the Stellaris LaunchPad. J1 and J2 are
1.8 inches apart and constitute the BoosterPack interface. J3 and J4 are 1.6 inches apart and constitute the BoosterPack XL Interface. Other major board signals are available on unpopulated headers on a 0.1 inch grid. Dimensions to these signals are provided for convenience. These signals are subject to change or move across revisions of the Stellaris LaunchPad or future
LaunchPads. It is recommended that BoosterPacks use only the BoosterPack interface and
BoosterPack XL Interface. Use of other pins and signals is acceptable but these pins and signals can change at any time.

Stellaris LaunchPad BoosterPack Development Guide
BoosterPack Design Guidelines
Follow these guidelines when designing your BoosterPack:
BoosterPacks should not extend more than 0.350 inches above the center of the top
BoosterPack interface pin.
BoosterPacks should not extend more than 0.150 inches below the center of the bottom pin of the BoosterPack interface.
Note: BoosterPacks that extend more than 0.150 inches below the center of the bottom pin will partially cover the Stellaris LaunchPad user switches which can result in lost user access to those user inputs.
BoosterPacks are not restricted in width and may extend as much as desired left and right of the Stellaris LaunchPad.
For BoosterPacks with RF antennas, place the antenna to the left or right of the Stellaris
LaunchPad for minimal interference and signal attenuation.
The BoosterPack interface does not provide any means of keying or alignment guidance. It is recommended that visual cues be provided on the BoosterPack to assist user in proper orientation of the BoosterPack.
If possible, design the BoosterPack so that incorrect mating to a Stellaris LaunchPad will not damage the BoosterPack.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
