    SimpleLink™ CC3120, CC3220 Wi-Fi® Internet-on-a chip™ Solution Built-In Security FeaturesThe SimpleLink™ Wi-Fi® CC3120 and CC3220 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™ CC3120 and CC3220 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 CC3120 and CC3220 (CC3x20) devices. The second part describes the file system, along with guidelines and considerations for system designers working with the CC3x20 devices.

User's Guides

    SimpleLink™ Wi-Fi® and Internet of Things CC3120 and CC3220 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.
    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 SDK This 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.
