    SimpleLink™ CC31xx, CC32xx Wi-Fi® Internet-on-a chip™ Solution Built-In Security Features The 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 Devices This 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.

    SimpleLink™ Wi-Fi® and Internet-of-Things CC31xx and CC32xx Network Processor This 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.
    CC3235 SimpleLink™ Wi-Fi® and Internet of Things Technical Reference Manual This technical reference manual details the modules and peripherals of the CC3235 SimpleLink™ Wi-Fi® MCU. Each description presents the module or peripheral in a general sense. Not all features and functions of all modules or peripherals may be present on all devices. Pin functions, internal signal connections, and operational parameters differ from device to device. The user should consult the device-specific data sheet for these details.
    SimpleLink™ Wi-Fi® and Internet-on-a chip™ CC3135 and CC3235 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 CC3235 devices, and the LaunchPad™ for CC3235 devices.
    CC3235MOD SimpleLink™ Wi-Fi® LaunchPad™ Development Kit The CC3235MOD SimpleLink LaunchPad™ Development Kit (LAUNCHCC3235MOD) is a low-cost evaluation platform for Arm®Cortex®-M4-based MCUs. The LaunchPad design highlights the CC3235MOD Internet-on-a chip™ solution and Dual-Band Wi-Fi capabilities. The CC3235MOD LaunchPad also features temperature and accelerometer sensors, programmable user buttons, an RGB LED for custom applications, and onboard emulation for debugging. The stackable headers of the CC3235MOD 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.
