Device and Documentation Support

TI offers an extensive line of development tools. Tools and software to evaluate the performance of the device, generate code, and develop solutions are listed in this section.

Tools and Software

Development Tools

    SimpleLink Studio for CC3120R The CC3120R device is supported.

    SimpleLink Studio for CC3120R is a Windows®-based software tool used to aid in the development of embedded networking applications and software for microcontrollers. Using SimpleLink Studio for CC3120R, embedded software developers can develop and test applications using any desktop IDE, such as Visual Studio or Eclipse, and connect their applications to the cloud using the CC3120R BoosterPack™ Plug-in Module. The application can then be easily ported to any microcontroller. With the SimpleLink Wi-Fi CC3120R solution, customers now have the flexibility to add Wi-Fi to any microcontroller (MCU). This Internet-on-a-chip solution contains all you need to easily create IoT solutions: security, quick connection, cloud support, and more. For more information on CC3120R, visit SimpleLink Wi-Fi Solutions.

    CC3120R Software Development Kit (SDK) The CC3120R device is supported.

    The SimpleLink Wi-Fi CC3220 SDK contains drivers for the CC3220 programmable MCU, 30+ sample applications, and documentation needed to use the solution. The SDK also contains the flash programmer, a command line tool for flashing software, configuring network and software parameters (SSID, access point channel, network profile, and so on), system files, and user files (certificates, web pages, and so on). This SDK can be used with TI’s SimpleLInk Wi-Fi CC3220 LaunchPad™ development kit.

    The SDK has a variety of support offerings. All sample applications in the SDK are supported on the integrated Cortex-M4 processor with CCS IDE and no RTOS. In addition, a few of the applications support IAR, Free RTOS, and TI-RTOS.

TI Designs and Reference Designs

The TI Designs Reference Design Library is a robust reference design library spanning analog, embedded processor, and connectivity. Created by TI experts to help you jumpstart your system design, all TI Designs include schematic or block diagrams, BOMs, and design files to speed your time to market.

Device Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of the CC3120R device and support tools (see Figure 7-1).

This guide does not provide a detailed description of the host driver APIs.
    SimpleLink™ Wi-Fi® CC3120 and CC3220 and IoT Solution Layout Guidelines This document provides the design guidelines of the 4-layer PCB used for the CC3120 and CC3220 SimpleLink Wi-Fi family of devices from Texas Instruments™. The CC3120 and CC3220 devices are easy to lay out and are available in quad flat no-leads (QFNS) packages. When designing the board, follow the suggestions in this document to optimize performance of the board.
    SimpleLink™ Wi-Fi® CC3120 Internet-on-a-chip™ Solution SDKThis guide is intended to help users in the initial setup and demonstration of the different demos in the CC3120 SDK. The guide lists the software and hardware components required to get started, and explains how to install the supported integrated development environment (IDE), SimpleLink CC3120 SDK, and the various other tools required.
    SimpleLink™ Wi-Fi® and Internet-on-a-chip™ CC3120 and CC3220 Solution Radio Tool The Radio Tool serves as a control panel for direct access to the radio, and can be used for both the radio frequency (RF) evaluation and for certification purposes. This guide describes how to have the tool work seamlessly on Texas Instruments ™ evaluation platforms such as the BoosterPack™ plus FTDI emulation board for CC3120 devices, and the LaunchPad™ for CC3220 devices.

Electrostatic Discharge Caution

esds-image

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
