Introduction

The SoC wireless MCU CC3220x device is available in three variants: CC3220R, CC3220S, and CC3220SF. The CC3220R features 256KB RAM, IoT network security, and device identity/key. The CC3220S builds on the CC3220R with MCU-level security (e.g., file system encryption, user IP [MCU image] encryption, secure boot, and debug security). The CC3220SF builds on the CC3220S and, in addition to 256KB RAM, integrates a user-dedicated 1MB executable flash. Start your IoT design with a Wi-Fi CERTIFIED wireless MCU. The SimpleLink Wi-Fi CC3220x device family is a SoC solution that integrates two processors on a single chip: • The application processor is an Arm Cortex-M4 MCU with user-dedicated 256KB RAM and optional 1MB serial flash. • The network processor MCU runs all Wi-Fi and Internet protocol 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 IoT connectivity. Key new features include: Optimized low-power management • Enhanced network security • Device identity and asymmetric key • Enhanced file system security (supported only on CC3220S and CC3220SF variants) • IPv6 TCP/IP stack Access point mode supporting 4 stations • Up to 16 BSD sockets open simultaneously, with 6 supporting secure (HTTPS) RESTful API support The CC3220x device family is part of the SimpleLink MCU platform — a universal, easy-to-use development environment built on a single SDK, a rich toolset, reference designs, and an E2E community, supporting Wi-Fi, low-power Bluetooth, Sub-1GHz devices, and host MCUs.
