Tiva™ C Series EK-TM4C123GXL LaunchPad:
BoosterPack Development Guide
The Texas Instruments’ Tiva™ C Series TM4C123G 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 (MCUs). The Tiva Series of 32-bit ARM® Cortex™-M4 MCU family expands that
success by introducing the Tiva C Series TM4C123G LaunchPad featuring the Tiva C Series
TM4C123GH6PM microcontroller.
Build your own BoosterPack and take advantage of Texas Instruments’ website to help promote it! From

LaunchPad and BoosterPack Expansion Concept and Overview
The Texas Instruments’ Tiva C Series TM4C123G LaunchPad concept is an extremely low-cost,
expandable evaluation system for TI's Tiva C Series of ARM 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® LM4F120 LaunchPad expanded on that success.
Now, the LaunchPad evaluation kit platform introduces the Tiva C Series EK-TM4C123GXL LaunchPad,
featuring the Tiva C Series TM4C123GH6PM MCU.
A Tiva C Series 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. These expansion headers are referred to as the BoosterPack Interface. A
BoosterPack is an expansion card designed for this interface. The BoosterPack interface provides a
mechanism for developers to easily extend the Tiva C Series LaunchPad with application- and userspecific functions.
The EK-TM4C123GXL LaunchPad provides a BoosterPack interface that is compatible with the MSP430
LaunchPad. In addition, the TM4C123 LaunchPad provides access to additional Tiva C Series
functionality through an extended BoosterPack interface called the BoosterPack XL Interface.
BoosterPack interfaces with highly similar functionality for expansion will be available for the Tiva C Series
LaunchPad, in addition to microcontroller-family-specific functionality available on a BoosterPack XL
Interface for additional options. Table 1 provides a summary of current BoosterPack interface
compatibility.

BoosterPack XL Functional Interface
www.ti.com

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 in (4,064 cm) apart directly inside of the MSP430 LaunchPad-compatible BoosterPack
interface headers. The pins are spaced on 0.10-inch (2,54-mm) centers. These inner 10-pin headers
(connectors J3 and J4) are not intended to be compatible with other TI LaunchPads or LaunchPad XL kits.
This feature is a Tiva C Series-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. The Tiva C Series board conforms to these recommendations. No effort has
been made to make this interface compatible with any other LaunchPad.
Table 4 and Table 5 show the Tiva C Series peripherals that are routed to each pin of the Tiva C Seriesonly 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 TM4C123GH6PM pin for one of
the functions found in the tables.

LaunchPad Power Interface
4
www.ti.com
LaunchPad Power Interface
The Tiva C Series 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 TM4C123G 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 mA at 5 V to
the Tiva C Series LaunchPad. The selected USB power source is made directly available to the
BoosterPack XL Interface on the J3.01 pin. This pin is a direct connection with only small decoupling
capacitors provided on the Tiva C Series LaunchPad.
All LaunchPads, including the TM4C123G LaunchPad, also provide a 3.3-V supply on pin J1.01 of the
BoosterPack Interface. On the Tiva C Series LaunchPad, this supply 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 mA 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,
approximately 300 mA to 350 mA are available to the BoosterPack Interface. Detailed power management
is the responsibility of the BoosterPack developer who must also manage the application to be run on the
target microcontroller.
The TM4C123G LaunchPad can be powered through an external supply on a BoosterPack. If providing
power to the Tiva C Series 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 TM4C123G LaunchPad voltage regulator. Providing only 3.3 V results in some lost functionality
(for example, the on-board LEDs may not illuminate). It may also result in reverse current leakage through
the on-board voltage regulator. Therefore, if providing power externally, it is recommended 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 pins 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 Tiva C Series LaunchPad. These pins 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.

Special Consideration for Shared Pins
www.ti.com

Special Consideration for Shared Pins
To provide compatibility with the MSP430 LaunchPad's BoosterPack interface as well as 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 the respective use of each is provided in Table 6.

Tiva C Series LaunchPad Dimensions and Mating
See Figure 2 for a dimensional drawing of the Stellaris LaunchPad. J1 and J2 are 1.8 in (4,572 cm) apart
and constitute the BoosterPack interface. J3 and J4 are 1.6 in (4,064 cm) apart and constitute the
BoosterPack XL Interface. Other major board signals are available on unpopulated headers on a 0.1-in
(2,54-mm) grid. Dimensions to these signals are provided for convenience. These signals are subject to
change or move across revisions of the Tiva C Series 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.

BoosterPack Design Guidelines
Follow these guidelines when designing your BoosterPack:
• BoosterPacks should not extend more than 0.350 in (8,89 mm) above the center of the top
BoosterPack Interface pin.
• BoosterPacks should not extend more than 0.150 in (3,81 mm) below the center of the bottom pin of
the BoosterPack Interface.
NOTE: BoosterPacks that extend more than 0.150 in (3,81 mm) below the center of the bottom pin
will partially cover the Tiva C Series LaunchPad user switches, which can result in lost user
access to those user inputs.
•
•
•
•
8
BoosterPacks are not restricted in width and may extend as much as desired left and right of the Tiva
C Series LaunchPad.
For BoosterPacks with RF antennas, place the antenna to the left or right of the Tiva C Series
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 Tiva C Series LaunchPad does not
damage the BoosterPack.

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 as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
