CC3200MOD SimpleLink™ Microcontroller and Wi-Fi®

Network Processor Module - LaunchPad Hardware

1 Introduction

1.1 CC3200MOD LaunchPad

Start your design with the CC3200 module LaunchPad (CC3200MODLAUNCHXL), which encapsulates

the industry’s first programmable wireless microcontroller (MCU) module with built-in Wi-Fi connectivity.

Created for the Internet of Things (IoT), the SimpleLink CC3200MOD is a wireless MCU module that

integrates an ARM Cortex-M4 MCU, allowing customers to develop an entire application using a single

device. The CC3200MOD integrates all required system-level hardware components including clocks, SPI

flash, RF switch, and all required passive components.

This document explains the various configurations of the CC3200MODLAUNCHXL, a low-cost evaluation

platform which hosts the CC3200MOD. The module LaunchPad also features programmable user buttons,

RGB LED for custom applications, temperature and accelerometer sensors, as well as onboard emulation

for debugging. The LaunchPad stackable headers interface demonstrates how to expand the functionality

of the CC3200MOD when interfacing with other peripherals on existing BoosterPack add-on boards, such

as graphical displays, audio codec, antenna selection, environmental sensing, and more. The

CC3200MODLAUNCHXL is provided as a complete platform solution including software, sample

applications, tools, user and programming guides, reference designs, and the TI E2E™ support

community. Figure 1 shows a photo of the CC3200MODLAUNCHXL board.

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.

2.3 Connecting a BoosterPack

A compatible BoosterPack can be stacked on top of the LaunchPad 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 the Vcc and 5V pins are aligned with the BoosterPack header pins. On the CC3200MOD

LaunchPad, a small white triangle symbol is provided near Pin-1 (see Figure 3) to orient all BoosterPacks.

This same marking, provided on compatible BoosterPacks, must be aligned before powering up the

boards.

Figure 3. Pn-1 Marking on the CC3200MOD LaunchPad (White Triangle)

2.4 Jumpers, Switches and LEDs

2.4.1 JTAG Headers

The headers are provided on the board to isolate the CC3200MOD 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

CC3200MOD device.

Figure 4. JTAG Headers

Table 1. JTAG Headers

Reference Usage Comments

J8 (TCK) (1) JTAG Short : Routes the on-board emulator to the CC3200MOD.

J9 (TMS)(1)

J10 (TDI) Open: Isolates the on-board emulator from the CC3200MOD.

J11 (TDO)

(1) For the SWD mode, only TCK and TMS need to be shorted to the CC3200MOD.

When a battery is used, disconnect all JTAG headers to prevent any reverse leakage current.

Hardware Description

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.

Figure 5. I2C Connections

By removing J2 and J3, the accelerometer and the temperature sensors are isolated from the I2C bus.

Note that this also removes any pull-up resistor from the I2C bus.

2.4.2.1 Jumper Settings

Table 2. Jumper Settings

Reference Usage Comments

Short : Connect the CC3200MOD I2C bus to the on-board sensors with

J2 I2C SDA pull-up

Open : Isolate the sensors from the CC3200MOD

Short : Connect the CC3200MOD I2C bus to the on-board sensors with

J3 I2C SCL pull-up

Open : Isolate the sensors from the CC3200MOD

J4 INT Short : Connect the accelerometer interrupt to the CC3200 on GPIO13

2.4.2.2 Default I2C Address

Table 3. Default I2C Addresses

Sensor Type Ref Part Number Slave Address

Temp sensor U6 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 CC3200MOD 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.

Short: Supply the board power from the on-board LDO.

J13 Board power 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)

Can be used to power the board from an external 2XAA battery

J20 3.3 V power input 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

Short 1-2: Route the signals to the 20 pin connector.

J6, J7 UART for Flash programming Short 2-3: Route the signals to the FTDI for Flash programming.

2.4.5 Sense on Power

The CC3200MOD 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 CC3200MOD device. The state of the device is

described in Table 6.

Table 6. SOP Lines

Usage Comments

100 = Flash programming

SOP[2:0] 000 = Functional mode + 4 Wire JTAG

001 = Functional mode + 2 Wire JTAG

Note: SOP[2:0] corresponds to J15, J16, and J17, in the LaunchPad schematic design.
