描述Start your design with the fully programmable FCC, IC, CE, MIC, and SRRC Certifiedwireless microcontroller (MCU) module with built-in Wi-Fi connectivity. Created for the IoT, theSimpleLink™ CC3220MODx and CC3220MODAx module family from TexasInstruments™ is a wireless module that integrates two physically separated on-chipMCUs. An application processor—ARM®Cortex®-M4 MCU with a user-dedicated 256KB of RAM, and an optional 1MBof Serial Flash.A network processor MCU to run allWi-Fi® and Internet logical layers. This ROM-based subsystem includes an802.11b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure internetconnections with 256-bit encryption. The CC3220MODx and CC3220MODAx wireless MCU family is a part of the second generationof the Internet-on-a chip™ family of solutions from TI. This generation introduces new features andcapabilities that further simplify the connectivity of things to the internet. The new capabilitiesinclude:IPv6 EnhancedWi-Fi provisioning Optimized low-powermanagementEnhanced file-systemsecurityWi-Fi AP connection with up to fourstationsMore concurrently opened BSD sockets—up to 16 BSDsockets (6 are secure HTTPS support) HTTPSsupportRESTful API supportAsymmetric keys crypto library   The CC3220MODx and CC3220MODAx wireless MCU family supports thefollowing modes: station, AP, and Wi-Fi Direct®. The CC3220MODx andCC3220MODAx modules also supports WPA2 personal and enterprise security. This subsystem includesembedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols. The modulesupports a variety of Wi-Fi provisioning methods, including HTTP based on AP mode, SmartConfig™technology, and WPS2.0.The power-management subsystem includes integrated DC/DC converters that support a widerange of supply voltages. This subsystem enables low-power consumption modes for extended batterylife, such as low-power deep sleep, hibernate with RTC (consuming only 5 µA), and shutdown mode(consuming only1 µA).The module includes a wide variety of peripherals, including a fast parallel camerainterface, I2S, SD, UART, SPI, I2C, and a 4-channel ADC.The SimpleLink CC3220MODx and CC3220MODAx module family come in four different modulevariants: CC3220MODS, CC3220MODSF, CC3220MODA, and CC3220MODASF.The CC3220MODS and CC3220MODAS modules include 256KB onapplication-dedicated embedded RAM for code and data. In addition, the CC3220MODAS includes anintegral antenna.The CC3220MODSF and CC3220MODASF modulesinclude application-dedicated 1MB of Serial Flash and 256KB of RAM for code and data. In addition,the CC3220MODASF includes an integral antenna. The four modules integrate the 40-MHz crystal, 32.768-kHz RTC clock, 32-Mb SPI serialFlash, RF filter, and passive components. The modules also have additional security features, suchas encrypted and authenticated file systems, user IP encryption and authentication, secured boot(authentication and integrity validation of the application image at Flash boot time), andmore.The CC3220MODx and CC3220MODAx devices are a part of the SimpleLink MCU platform, whichconsists of Wi-Fi, Bluetooth® low energy, Sub-1 GHz, and host MCUs. All share acommon, easy-to-use development environment with a single core software development kit (SDK) andrich tool set. A one-time integration of the SimpleLink platform lets you add any combination ofdevices from the portfolio into your design. The ultimate goal of the SimpleLink platform is toachieve 100 percent code reuse when your design requirements change.The CC3220MODx and CC3220MODAx module family is a complete platform solution includingsoftware, sample applications, tools, user and programming guides, reference designs, and theE2E™ online community. The module family is also part of theSimpleLink MCU portfolio and supports the SimpleLink developers ecosystem.
