SimpleLink™ 32-bit Arm Cortex-M4 Wi-Fi® wireless MCU with secure boot 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. For more information, visit the SimpleLink™ MCU
