CC3120/CC3220 SimpleLink™ Microcontrollers (MCUs)

Texas Instruments' CC3120/CC3220 devices are part of the SimpleLink microcontroller (MCU) platform which consists of Wi-Fi, low energy, sub-1 GHz and host MCUs, which all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich tool set. A one-time integration of the SimpleLink platform enables the user to add any combination of the portfolio’s devices into their design, allowing 100 percent code reuse when the design requirements change.
