Functional Description
2.1.1 Microcontroller
The TM4C1294NCPDTI is a 32-bit ARM Cortex-M4F based microcontroller with 1024-kB Flash memory,
256-kB SRAM, 6-kB EEPROM, and 120 MHz operation; integrated 10/100 Ethernet MAC and PHY;
integrated USB 2.0 connectivity with external high-speed USB 3.0 PHY capability; a hibernation module, a
multitude of serial connectivity and motion control PWM; as well as a wide range of other peripherals. See
the TM4C1294NCPDTI microcontroller data sheet for more complete details.
Most of the microcontroller’s signals are routed to 0.1-in (2.54-mm) pitch headers or through-hole solder
pads. An internal multiplexor 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 TM4C1294NCPDTI 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. The quickstart application automatically
connects to http://ti.exosite.com when an internet connection is provided through the RJ45 Ethernet jack
on the evaluation board.

2.1.2 Ethernet Connectivity
The Connected LaunchPad is designed to connect directly to an Ethernet network using RJ45 style
connectors. The microcontroller contains a fully integrated Ethernet MAC and PHY. This integration
creates a simple, elegant and cost-saving Ethernet circuit design. Example code is available for both the
uIP and LwIP TCP/IP protocol stacks. The embedded Ethernet on this device can be programmed to act
as an HTTP server, client or both. The design and integration of the circuit and microcontroller also enable
users to synchronize events over the network using the IEEE1588 precision time protocol.
When configured for Ethernet operation, it is recommended that the user configure LED D3 and D4 to be
controlled by the Ethernet MAC to indicate connection and transmit/receive status.
2.1.3 USB Connectivity
The Connected LaunchPad is designed to be USB 2.0 ready. A TPS2052B load switch is connected to
and controlled by the microcontroller USB peripheral, which manages power to the USB micro A/B
connector when functioning in a USB host. When functioning as a USB device, the entire Connected
LaunchPad can be powered directly from the USB micro A/B connector. Use JP1 to select the desired
power source.
USB 2.0 functionality is provided and supported directly out of the box with the target USB micro A/B
connector. High-speed USB 3.0 functionality can be enabled by adding an external USB PHY. The USB
external PHY control and data signals are provided on the breadboard expansion header X11.
2.1.4 Motion Control
The Connected LaunchPad includes the Tiva C Series Motion Control PWM technology, featuring a PWM
module capable of generating eight PWM outputs. The PWM module provides a great deal of flexibility
and can generate simple PWM signals – for example, those required by a simple charge pump – as well
as paired PWM signals with dead-band delays, such as those required by a half-H bridge driver. Three
generator blocks can also generate the full six channels of gate controls required by a 3-phase inverter
bridge.
A quadrature encoder interface (QEI) is also available to provide motion control feedback.
See the BoosterPacks and Headers section of this document for details about the availability of these
signals on the BoosterPack interfaces.
2.1.5 User Switches and LED's
Two user switches are provided for input and control of the TM4C1294NCPDTI software. The switches
are connected to GPIO pins PJ0 and PJ1.
A reset switch and a wake switch are also provided. The reset switch initiates a system reset of the
microcontroller whenever it is pressed and released. Pressing the reset switch also asserts the reset
signal to the BoosterPack and Breadboard headers. The wake switch is one way to bring the device out of
hibernate mode.
Four user LEDs are provided on the board. D1 and D2 are connected to GPIOs PN1 and PN0. These
LEDs are dedicated for use by the software application. D3 and D4 are connected to GPIOs PF4 and
PF0, which can be controlled by user’s software or the integrated Ethernet module of the microcontroller.
A power LED is also provided to indicate that 3.3 volt power is present on the board.

2.1.6.2
BoosterPack 2
The second BoosterPack XL interface is located near the middle of the board. This interface is fully compliant with the BoosterPack standard, and
adds features not covered by the BoosterPack standard that enable operation with additional BoosterPacks.
An additional analog signal is provided on the outer left header (X6-9). This signal can be used to monitor the touch panel on the popular Kentec
EB-LM4F120-L35 BoosterPack.
Using the jumpers JP4 and JP5, Controller Area Network (CAN) digital receive and transmit signals can be optionally routed to the BoosterPack 2
interface. The location of these signals is consistent with the CAN interface on the Tiva C Series TM4C123G LaunchPad and the Stellaris
LM4F120 LaunchPad. In the default configuration, UART0 is used for the ICDI virtual UART and CAN is not present on the BoosterPack headers.
In this configuration, the ROM serial bootloader can be used over the ICDI virtual UART. When the jumpers are configured for CAN on the
BoosterPack, then UART4 must be used for the ICDI virtual UART.
To comply with both the original and the new BoosterPack standard, I2C is provided on both sides of the BoosterPack connection. Use of I2C on
the bottom left of the BoosterPack connection is highly encouraged where possible, to be in compliance with the new BoosterPack standard. To
provide I2C capability on the right side of the connector, per the original standard, two zero-ohm resistors (R19 and R20) are used to combine the
SPI and I2C signals. These signals are not shared with any other pins on the LaunchPad and therefore removal of these zero-ohm resistors
should not be required. Software should be certain that unused GPIO signals are configured as inputs.
Table 2-2 provides a complete listing of the BoosterPack pins and the GPIO alternate functions available at each pin. The TM4C1294NCPDT
GPIO register GPIOPCTL values are shown for each configuration. The headers in this table are labeled from left to right in ten pin columns. ‘A’
and ‘D’ make up the outer BoosterPack standard pins, ‘B’ and ‘C’ make up the inner BoosterPack XL standard pins.

2.1.6.3
Breadboard Connection
The breadboard adapter section of the board is a set of 98 holes on a 0.1 inch grid. Properly combined with a pair of right angle headers, the
entire Connected LaunchPad can be plugged directly into a standard 300 mil (0.3 inch) wide solder-less breadboard. The right angle headers and
breadboard are not provided with this kit. Suggested part numbers are Samtec TSW-149-09-L-S-RE and TSW-149-08-L-S-RA right angle pin
headers and Twin industries TW-E40-1020 solder-less breadboard. Samtec TSW-149-09-F-S-RE and TSW-149-09-F-S-RA may be substituted.
A detailed explanation of how to install the headers is available on the TI LaunchPad Wiki or at
http://users.ece.utexas.edu/~valvano/EE345L/Labs/Fall2011/LM3S1968soldering.pdf.
Nearly all microcontroller signals are made available at the breadboard adapter holes (X11). These signals are grouped by function where
possible. For example, all EPI signals are grouped on one side of the connector. Many of the analog signals are grouped near VREF, and UART,
SSI and I2C signals are grouped by peripheral to make expansion and customization simpler.
Table 2-3 and Table 2-4 show the GPIO pin and signal muxing for the X11 breadboard adapter pads.

2.1.6.4
Other Headers and Jumpers
JP1 is provided to select the power input source for the Connected LaunchPad. The top position is for
BoosterPack power; this position also disconnects both USB voltages from the board’s primary 5-volt
input. In the top position, the TPS2052B does not limit current so additional care should be exercised. The
middle position draws power from the USB connector on the left side of the board near the Ethernet jack.
The bottom position is the default, in which power is drawn from the ICDI (Debug) USB connection.
JP2 separates the MCU 3.3-volt power domain from the rest of the 3.3-volt power on the board allowing
an ammeter to be used to obtain more accurate measurements of microcontroller power consumption.
JP3 isolates the output of the TPS73733 LDO from the board’s 3.3-V power domain.
JP4 and JP5 are used to configure CAN signals to the BoosterPack 2 interface. In the default horizontal
configuration, CAN is not present on the BoosterPack. UART 4 goes to the BoosterPack and UART 0
goes to the ICDI virtual serial port to provide ROM serial bootloader capability. In the vertical CAN-enabled
configuration, UART 4 goes to the ICDI virtual serial port and CAN signals are available on the
BoosterPack. The ROM serial bootloader is not available to the ICDI virtual serial port while the jumpers
are in the CAN position.
Figure 2-2 shows the default configuration and relative location of the jumpers on the board.

Power Management
2.2.1 Power Supplies
The Connected LaunchPad can be powered from three different input options:
• On-board ICDI USB cable (Debug, Default)
• Target USB cable
• BoosterPack or Breadboard adapter connection
The JP1 power-select jumper is used to select one of the power sources.
In addition, the JP3 power jumper can be used to isolate the 3.3-volt output of the TPS73733 from the
board’s 3.3-volt rail.
A TPS2052B load switch is used to regulate and control power to the Target USB connector when the
microcontroller is acting in USB host mode. This load switch also limits current to the BoosterPack and
Breadboard adapter headers when the JP1 jumper is in the ICDI position.

Power Management

2.2.2 Low Power Modes
The Connected LaunchPad demonstrates several low power microcontroller modes. In run mode, the
microcontroller can be clocked from several sources such as the internal precision oscillator or an external
crystal oscillator. Either of these sources can then optionally drive an internal PLL to increase the effective
frequency of the system up to 120 MHz. In this way, the run mode clock speed can be used to manage
run mode current consumption.
The microcontroller also provides sleep and deep sleep modes and internal voltage adjustments to the
flash and SRAM to further refine power consumption when the processor is not in use but peripherals
must remain active. Each peripheral can be individually clock gated in these modes so that current
consumption by unused peripherals is minimized. A wide variety of conditions from internal and external
sources can trigger a return to run mode.
The lowest power setting of the microcontroller is hibernation, which requires a small amount of supporting
external circuitry available on the Connected LaunchPad. The Connected LaunchPad can achieve
microcontroller current consumption modes under 2 micro-Amps using hibernate VDD3ON mode.
Hibernation with VDD3ON mode is not supported on this board. The Connected LaunchPad can be woken
from hibernate by several triggers including the dedicated wake button, the reset button, an internal RTC
timer and a subset of the device GPIO pins. The hibernation module provides a small area of internal
SRAM that can preserve data through a hibernate cycle.
2.2.3 Clocking
The Connected LaunchPad uses a 25 MHz crystal (Y1) to drive the main TM4C1294NCPDTI internal
clock circuit. Most software examples use the internal PLL to multiply this clock to higher frequencies up to
120 MHz for core and peripheral timing. The 25-MHz crystal is required when using the integrated
Ethernet MAC and PHY.
The Hibernation module is clocked from an external 32.768-KHz crystal (Y3).
2.2.4 Reset
The RESET signal to the TM4C1294NCPDTI microcontroller connects to the RESET switch, BoosterPack
connectors, Breadboard adapter and to the ICDI circuit for a debugger-controller reset.
External reset is asserted (active low) under the following conditions:
• Power-on reset (filtered by and R-C network)
• RESET switch is held down.
• By the ICDI circuit when instructed by the debugger (this capability is optional, and may not be
supported by all debuggers)
• By an external circuit attached to the BoosterPack or Breadboard connectors.
2.3
Debug Interface
2.3.1 In-Circuit Debug Interface (ICDI)
The Connected LaunchPad comes with an on-board ICDI. The ICDI allows for the programming and
debugging of the TM4C1294NCPDTI using LM Flash Programmer and/or any of the supported tool
chains. Note that ICDI only supports JTAG debugging at this time. It is possible to use other JTAG
emulators instead of the on board ICDI, by connecting to U6. When the ICDI detects an external debug
adapter connection on the JTAG connector U6 and disables the ICDI outputs to allow the external debug
adapter to drive the debug circuit. For more information, see Section 2.3.2.
Debug out of the ICDI is possible by removing resistors R6, R7, R8, R10, R11, R15, R16 and R40 from
the Connected LaunchPad and use the ICDI to drive JTAG signals out on U6 for the purpose of
programming or debugging other boards. To restore the connection to the on-board TM4C1294NCPDTI
microcontroller, install jumpers from the odd to even pins of X1 or re-install the resistors. Removal of R40
disables the detection of an attached external debugger. R40 must be installed to use an external debug
adapter to program or debug the Connected LaunchPad.

Debug Interface
www.ti.com
2.3.2 External Debugger
The connector U6 is provided for the attachment of an external debug adapter such as the IAR J-Link or
Keil ULINK. This connector follows the ARM standard 10-pin JTAG pinout. This interface can use either
JTAG or SWD if supported by the external debug adapter.
2.3.3 Virtual COM Port
When plugged into a USB host, the ICDI enumerates as both a debugger and a virtual COM port. JP4 and
JP5 control the selection of which UART from the TM4C1294NCPDTI is connected to the virtual COM
port. In the default configuration, UART0 maps to the virtual COM port of the ICDI. In the CAN jumper
configuration, UART4 maps to the virtual COM port of the ICDI.

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 JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. 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 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.
