SimpleLink™ 32-bit Arm Cortex-M4 Wi-Fi® wireless MCU with 1MB Flash and 256kB RAM

The SoC Wireless MCU CC3220x device comes in three variants: CC3220R, CC3220S, and C3220SF.

* CC3220R features 256KB of RAM, IoT networking security and device identity/keys. * CC3220S builds on the CC3220R and MCU level security such as file system encryption, user IP (MCU image) encryption, secure boot and debug security. * CC3220SF builds on the CC3220S and integrates a user-dedicated 1MB of executable Flash, in addition to the 256KB of RAM. Start your internet-of-things (IoT) design with a Wi-Fi CERTIFIED™ Wireless Microcontroller. The SimpleLink™ Wi-Fi® CC3220x device family is a system-on-chip (SoC) solution, that integrates two processors within a single-chip:

* The application processor is an Arm® Cortex®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of serial flash. * The network processor MCU runs 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. These devices introduce new features and capabilities that further simplify the connectivity of things to the internet. The main new features include the following:

* Optimized low-power management * Enhanced networking security * Device identity and Asymmetric keys * Enhanced file system security (supported only by the CC3220S and CC3220SF variants) * IPv6 TCP/IP Stack * AP mode with support of four stations * Up to 16 concurrent BSD sockets, of which 6 are secure * HTTPS support * RESTful API support The CC3220x device family is part of the SimpleLink™ MCU platform, a common, easy-to-use development environment based on a single core software development kit (SDK), rich tool set, reference designs and E2E™ community that supports Wi-Fi®, Bluetooth® low energy, Sub-1 GHz and host MCUs.
