描述 The CC3120R device is part of the SimpleLink™ microcontroller (MCU) platform which consists of Wi-Fi,low energy, Sub-1 GHz and host MCUs, which 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 portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change. For more information, visit Overview for SimpleLink™ solutions. 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. 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 the new features and enhanced capabilities, such as the following: IPv6 Enhanced Wi-Fi provisioning Enhanced power consumption Wi-Fi AP connection with up to four stations More concurrently opened BSD sockets; up to 16 BSD sockets, of which 6 aresecure HTTPS support RESTful API support Asymmetric keys crypto libraryThe 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 (C89) and requires minimal platform adaptation layer (porting layer). The driver has a small memory footprint and can run on 8-, 16-, or 32-bit microcontrollers 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.特性CC3120R SimpleLink™ Wi-Fi® Consists of a Wireless Network Processor (NWP) andPower-Management Subsystems Featuring Wi-FiInternet-on-a chip™ DedicatedARM®Cortex®-M3 Microcontroller Unit (MCU)Completely Offloads Wi-Fi and Internet Protocols from the Application MCU Wi-Fi Modes: 802.11b/g/n Station 802.11b/g Access Point (AP) Supports up to Four StationsWi-Fi Direct Client/Group Owner WPA2 Personal and EnterpriseSecurity: WEP, WPA/WPA2 PSK, WPA2 Enterprise (802.1x) IPv4 andIPv6 TCP/IP StackIndustry-Standard BSD Socket Application Programming Interfaces (APIs)16 Simultaneous TCP or UDP Sockets6 Simultaneous TLS and SSL SocketsIP Addressing: Static IP, LLA,DHCPv4, and DHCPv6 With Duplicate Address Detection (DAD) SimpleLink Connection Manager for Autonomous and Fast Wi-FiConnections Flexible Wi-Fi Provisioning WithSmartConfig Technology, AP Mode, and WPS2Options RESTful API Support Using Internal HTTPServer Wide Set of SecurityFeatures Hardware Features Separate Execution Environments Device Identity Networking securityPersonal and Enterprise Wi-Fi Security Secure Sockets (SSLv3, TLS1.0/1.1/TLS1.2) HTTPS Server Trusted Root-Certificate Catalog TI Root-of-Trust Public key Software IP protectionSecure Key StorageFile System Security Software Tamper Detection Cloning ProtectionEmbedded Network ApplicationsRunning on the Dedicated NWPHTTP/HTTPS Web Server With Dynamic User CallbacksmDNS, DNS-SD, DHCP Server Ping Recovery Mechanism—Can Recover toFactory Defaults or to a Complete Factory Image Wi-Fi TXPower18.0 dBm @ 1 DSSS 14.5 dBm @ 54 OFDM Wi-Fi RX Sensitivity–96.0 dBm @ 1 DSSS–74.5 dBm @ 54 OFDM Application ThroughputUDP: 16 Mbps TCP: 13 Mbps Power-Management SubsystemIntegrated DC-DC Converters Support a Wide Range of Supply Voltage: VBAT Wide-Voltage Mode: 2.1 V to 3.6 V VIO is Always Tied With VBAT Preregulated 1.85-V ModeAdvanced Low-Power ModesShutdown: 1 µA Hibernate: 4.5 µA Low-Power Deep Sleep (LPDS): 115 µA RX Traffic: 59 mA @ 54 OFDM TX Traffic: 229 mA @ 54 OFDM, Maximum Power Idle Connected (MCU in LPDS): 690 µA @ DTIM = 1Clock Source40.0-MHz Crystal With Internal Oscillator 32.768-kHz Crystal or External RTC RGK Package64-Pin, 9-mm × 9-mm Very Thin Quad Flat Nonleaded (VQFN) Package, 0.5-mm Pitch OperatingTemperatureAmbient Temperature Range: –40°C to +85°C DeviceSupports SimpleLink Developers Ecosystem All trademarks are the property of their respective owners.
