Texas Instruments CC3120R SimpleLink™ Wi-Fi Network Processor

Texas Instruments CC3120 SimpleLink™ Wi-Fi Network Processor consists of Wi-Fi, low energy, Sub-1GHz and host MCUs, which all share a common, easy-to-use development environment. This device comes with a single core software development kit (SDK) and rich toolset. A one-time integration of the SimpleLink platform enables the addition of any combination of the SimpleLink’s devices into a design. This feature allows for 100 percent code reuse when the design requirements change. With the CC3120, a designer can connect any microcontroller (MCU) to the Internet of Things (IoT) cloud. The Wi-Fi® Alliance CERTIFIED® Texas Instruments CC3120 device is part of the second generation of the SimpleLink Wi-Fi family that dramatically simplifies the implementation of low-power Internet connectivity.
