CC3120中文资料适用于 MCU 应用的 SimpleLink™ Wi-Fi® 网络处理器、物联网解决方案数据手册TI规格书

描述 Description

The CC3120R device is part of the SimpleLink™ microcontroller (MCU) platform that consists of Wi-Fi®,Bluetoothlow energy, Sub-1 GHz and host MCUs. 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 devices from the portfolio into your design, allowing 100 percent code reuse when your design requirements change.

Connect any microcontroller (MCU) to the internet-of-things (IoT) cloud with the CC3120R device from Texas Instruments™. The Wi-Fi Alliance®-certified CC3120R device is part of the second generation of the SimpleLink™ Wi-Fi® family that dramatically simplifies the implementation of low-power internet connectivity.

The CC3120R has all of the Wi-Fi and internet protocols implemented in the ROM, which runs from the dedicated on-chip Arm® network processor and significantly offloads the host MCU and simplifies the system integration.

The CC3120R Wi-Fi® Internet-on-a chip™ device contains a dedicated Arm® MCU that offloads many of the networking activities from the host MCU. This 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 CC3120R device supports station, AP, and Wi-Fi direct modes. The device also supports WPA2™ personal and enterprise security and WPA3™ personal and enterprise. The device includes embedded TCP/IP and TLS/SSL stacks, an HTTP server, and multiple internet protocols. The CC3120R device supports a variety of Wi-Fi provisioning methods, including HTTP based on AP mode, SmartConfig™ technology, and WPS2.0.

As part of TI’s SimpleLink™ Wi-Fi® family second generation, the CC3120R device introduces new features and enhanced capabilities, such as the following:

IPv6 Enhanced Wi-Fi provisioning Optimized low-power management 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 CC3120R device is delivered with a slim and user-friendly host driver to simplify the integration and development of networking applications. The host driver can easily be ported to most platforms and operating systems (OS). The driver is written in strict ANSI-C (C99) programming language and requires a minimal platform adaptation layer (porting layer). The driver has a small memory footprint and can run on 8-, 16-, or 32-bit MCUs with any clock speed (no performance or real-time dependency).

The CC3120R device comes in an easy-to-layout VQFN package and is delivered as a complete platform solution, including various tools and software, sample applications, user and programming guides, reference designs, and the TI E2E™ support community. The CC3120R device is part of the SimpleLink MCU Ecosystem.
