3 Description

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.
