CC3200 SimpleLink™ Wi-Fi®and Internet of Things
Solution With MCU LaunchPad™ Hardware
1 Introduction
1.1 CC3200 LaunchPad Development Kit
The high-performance CC3200 is the industry's first single-chip microcontroller (MCU) with built-in Wi-Fi®
connectivity for the LaunchPad™ ecosystem. Created for the Internet of Things (IoT), the SimpleLink Wi-
Fi CC3200 device is a wireless MCU that integrates a high-performance Arm®Cortex®-M4 MCU allowing
customers to develop an entire application with a single IC. With on-chip Wi-Fi, internet, and robust
security protocols, no prior Wi-Fi experience is needed for faster development.
The CC3200 LaunchPad development kit is a low-cost evaluation platform for Arm Cortex-M4F-based
microcontrollers. The LaunchPad kit design highlights the CC3200 Internet-on-a-chip™ solution and Wi-Fi
capabilities. The CC3200 LaunchPad kit also features programmable user buttons, RGB LED for custom
applications, and onboard emulation for debugging. The stackable headers of the CC3200 LaunchPad XL
interface demonstrate how easy it is to expand the functionality of the LaunchPad kit when interfacing with
other peripherals on many existing BoosterPack™ plug-in modules, such as graphical displays, audio
codecs, antenna selection, environmental sensing, and more. Figure 1 shows a photo of the CC3200
LaunchPad kit.
Free software development tools are also available, including TI’s Eclipse-based Code Composer
Studio™ and IAR Embedded Workbench®. More information about the LaunchPad kit, the supported
BoosterPack modules, and the available resources can be found at TI’s LaunchPad portal. Also visit the
CC3200 Wiki page for design resources and example projects.
NOTE: The antennas used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons and must not be co-located or operating in conjunction with
any other antenna or transmitter.
NOTE: All figures and references in this document apply to the Rev3.2. Most of the document also
applies to the Rev4.1, unless otherwise stated. For the exact list of changes made across
board revisions, refer to Section 2.8.2.

• On-board accelerometer and temperature sensor for out-of-box demo, with option to isolate them from
the inter-integrated circuit (I2C) bus
• Micro USB connector for power and debug connections
• Headers for current measurement and external JTAG connection
• Bus-powered device with no external power required for Wi-Fi
• Long-range transmission with highly optimized antenna (200 m typical in open air with a 6-dBi antenna
AP)

2.3 Connecting a BoosterPack Plug-in Module
A compatible BoosterPack module can be stacked on top of the LaunchPad kit using the 2x20 pin
connectors. Note that the connectors do not have a key to prevent the misalignment of the pins or reverse
connection. Ensure that VCC and 5V pins are aligned with the BoosterPack module header pins. On the
CC3200 LaunchPad kit, a small white triangle symbol is provided near Pin-1 (see Figure 3) to orient all
BoosterPack modules. This same marking, provided on compatible BoosterPack modules, must be
aligned before powering up the boards.

2.4 Jumpers, Switches, and LEDs
2.4.1 JTAG Headers
The headers are provided on the board to isolate the CC3200 device from the mounted FTDI JTAG
emulator. These jumpers are shorted by default when the board is shipped from TI. To connect an
external emulator, remove these jumpers and place the external emulator on the pins closer to the
CC3200 device. When a battery is used, disconnect all the JTAG headers to prevent any reverse leakage
current.
Figure 4. JTAG Headers
(1) For the SWD mode, only TCK and TMS must be shorted to the CC3200.
Table 1. JTAG Headers
Reference Usage Comments
J8 (TCK) (1) JTAG Short: Routes the on-board emulator to the CC3200
J9 (TMS) (1)
J10 (TDI) Open: Isolate the on-board emulator from the CC3200.
J11(TDO)
2.4.2 I2C Connections
The board features an accelerometer and a temperature sensor for the out-of-box demo. These are
connected to the I2C bus and can be isolated using the jumpers provided. By removing J2 and J3, the
accelerometer and the temperature sensors are isolated from the I2C bus. This also removes any pullup
resistor from the I2C bus.

Sensor Type Ref Part Number Slave Address
Temp sensor U6(1) TMP008 0x41
Accelerometer U10 BMA222 0x18
2.4.3 Power Connections
The board can be powered by using the on-board micro USB connector. An on-board LDO provides 3.3 V
for the CC3200 and the rest of the board to operate. This supply can be isolated from the LDO using the
jumpers on the board.
Table 4. Jumper Settings
Reference Usage Comments
J12 Current
measurement Measures the current flowing into the CC3200 device.
J13 Board power Short: Supply the board power from the on-board LDO.
Open: Supply the board power from the J20 (battery connector)
J19 5-V power 5-V output from the USB VBUS (has a diode drop of up to 0.4 V)
J20 3.3-V power input Can be used to power the board from an external 2xAA battery pack. It has in-built reverse
voltage protection to prevent the battery from being plugged in the reverse manner.

2.4.4 UART Signals
The board supports a USB-based virtual COM port, which is used on the FTDI device FT2232D. There
are two ports on the FT2232: the first port is dedicated for the emulation (JTAG/SWD) and the second port
is used for the virtual COM port. The UART can also be routed to the 20-pin connector and the selection
is performed using jumpers on the board.
Figure 6. UART Signals
Table 5. UART Signals
Reference Usage Comments
J6, J7 UART for flash
programming Short 1-2: Route the signals to the 20-pin connector. Short 2-3: Route the signals to the FTDI for flash programming.
2.4.5 Sense on Power
The CC3200 can be set to operate in three different modes based on the state of the sense-on-power
(SOP) lines. These are pins 21, 34, and 35 on the CC3200 device. The state of the device is described in
Table 6.
Table 6. SOP Lines
Usage Comments
SOP[2:0] 100 = Flash programming 000 = Functional mode + 4-Wire JTAG
001 = Functional mode + 2-Wire JTAG
SOP[2:0] corresponds to J15, J16, and J17 in the LaunchPad kit schematic design.
