Documentation Support

To receive notification of documentation updates—including silicon errata—go to the product folder for your device on ti.com (CC3235). In the upper right corner, click the "Alert me" button. This registers you to receive a weekly digest of product information that has changed (if any). For change details, check the revision history of any revised document. The current documentation that describes the processor, related peripherals, and other technical collateral follows.

The following documents provide support for the CC3235 device.

 

Application Reports

    SimpleLink™ CC31xx, CC32xx Wi-Fi® Internet-on-a chip™ Solution Built-In Security FeaturesThe SimpleLink Wi-Fi CC31xx and CC32xx Internet-on-a chip family of devices from Texas Instruments offer a wide range of built-in security features to help developers address a variety of security needs, which is achieved without any processing burden on the main microcontroller (MCU). This document describes these security-related features and provides recommendations for leveraging each in the context of practical system implementation.
    Using Serial Flash on SimpleLink™ CC3135 and CC3235 Wi-Fi® and Internet-of-Things DevicesThis application note is divided into two parts. The first part provides important guidelines and best- practice design techniques to consider when choosing and embedding a serial Flash paired with the CC3135 and CC3235 (CC3x35) devices. The second part describes the file system, along with guidelines and considerations for system designers working with the CC3x35 devices.

User's Guides

    SimpleLink™ Wi-Fi® and Internet-of-Things CC31xx and CC32xx Network ProcessorThis document provides software (SW) programmers with all of the required knowledge for working with the networking subsystem of the SimpleLink Wi-Fi devices. This guide provides basic guidelines for writing robust, optimized networking host applications, and describes the capabilities of the networking subsystem. The guide contains some example code snapshots, to give users an idea of how to work with the host driver. More comprehensive code examples can be found in the formal software development kit (SDK). This guide does not provide a detailed description of the host driver APIs.
    SimpleLink™ Wi-Fi® CC3135 and CC3235 and IoT Solution Layout GuidelinesThis document provides the design guidelines of the 4-layer PCB used for the CC3135 and CC3235 SimpleLink Wi-Fi family of devices from Texas Instruments. The CC3135 and CC3235 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™ CC3235 Wi-Fi® LaunchPad™ Development Kit HardwareThe CC3235 SimpleLink LaunchPad Development Kit (LAUNCHXL-CC3235) is a cost-conscious evaluation platform for Arm Cortex-M4-based MCUs. The LaunchPad design highlights the CC3235 Internet-on-a chip solution and Wi-Fi capabilities. The CC3235 LaunchPad also features temperature and accelerometer sensors, programmable user buttons, three LEDs for custom applications, and onboard emulation for debugging. The stackable headers of the CC3235 LaunchPad XL interface demonstrate how easy it is to expand the functionality of the LaunchPad when interfacing with other peripherals on many existing BoosterPack™ Plug-in Module add-on boards, such as graphical displays, audio codecs, antenna selection, environmental sensing, and more.
    SimpleLink™ Wi-Fi® and Internet-on-a chip™ CC3135 and CC3235 Solution Radio ToolThe 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 CC3235 devices, and the LaunchPad™ for CC3235 devices.
