Texas Instruments CC3220

The CC3220x device is 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 rich tool set. A one-time integration of the SimpleLink platform enables you to add any combination of the portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change.

Start your Internet-of-Things (IoT) design with a Wi-Fi® CERTIFIED® single-chip MCU System-on-Chip (SoC) with built-in Wi-Fi connectivity. Created for the IoT, the SimpleLink™ CC3220x device family from Texas Instruments is a single-chip solution, integrating two physically separated, on-chip MCUs. An application processor – ARM® Cortex®-M4 MCU with a user-dedicated 256KB of RAM, and an optional 1MB of XIP flash.A network processor MCU to run all Wi-Fi and Internet logical layers. This ROM-based subsystem includes an 802.11b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure internet connections with 256-bit encryption.

The CC3220x wireless MCU family is part of the second generation of TI’s Internet-on-a-chip™ family of solutions. This generation introduces new features and capabilities that further simplify the connectivity of things to the Internet. The new capabilities including the following:

Enhanced Wi-Fi provisioning
Enhanced power consumption
Enhanced file system security (supported only by the CC3220S and CC3220SF devices)
Wi-Fi AP connection with up to four stations
More concurrently opened BSD sockets; up to 16 BSD sockets, of which 6 are secure
HTTPS support
RESTful API support
Asymmetric keys crypto library

The CC3220x wireless MCU family supports the following modes: station, AP, and Wi-Fi Direct®. The device also supports WPA2 personal and enterprise security. This subsystem includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols. The device supports a variety of Wi-Fi provisioning methods including HTTP based on AP mode, SmartConfig™ Technology, and WPS2.0.
