描述The CC3220x 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. Start your Internet-of-Things (IoT) design with a Wi-Fi® CERTIFIED® single-chip MCU System-on-Chip (SoC) with built-in Wi-Fi connectivity. Created for the IoT, the SimpleLink™ CC3220x device family from Texas Instruments is a single-chip solution, integrating two physically separated, on-chip MCUs. An application processor – ARM® Cortex®-M4 MCU with a user-dedicated 256KB of RAM, and an optional 1MB of XIP flash.A network processor MCU to run 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 for fast, secure internet connections with 256-bit encryption. The CC3220x wireless MCU family is part of the second generation of TI’s Internet-on-a-chip™ family of solutions. This generation introduces new features and capabilities that further simplify the connectivity of things to the Internet. The new capabilities including the following: IPv6 Enhanced Wi-Fi provisioning Enhanced power consumption Enhanced file system security (supported only by the CC3220S and CC3220SFdevices) 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 library The CC3220x wireless MCU family supports the following modes: station, AP, and Wi-Fi Direct®. The device also supports WPA2 personal and enterprise security. This subsystem includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols. The device supports 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 wide range of supply voltages. This subsystem enables low-power consumption modes for extended battery life, such as low-power deep sleep, hibernate with RTC (consuming only 4.5 µA), and shutdown mode (consuming only 1 µA). The device includes a wide variety of peripherals, including a fast parallel camera interface, I2S, SD, UART, SPI, I2C, and 4-channel ADC. The SimpleLink CC3220x device family comes in three different device variants: CC3220R, CC3220S, and CC3220SF. The CC3220R and CC3220S devices include 256KB of application-dedicated embedded RAM for code and data, ROM with external serial flash bootloader, and peripheral drivers. The CC3220SF device includes application-dedicated 1MB of XIP flash and 256KB of RAM for code and data, ROM with external serial flash bootloader, and peripheral drivers. The CC3220S and CC3220SF device options have additional security features, such as encrypted and authenticated file systems, user IP encryption and authentication, secured boot (authentication and integrity validation of the application image at flash and boot time), and more. The CC3220x device family is a complete platform solution including software, sample applications, tools, user and programming guides, reference designs, and the E2E™ online community. The device family is also part of the SimpleLink MCU portfolio and supports the SimpleLink developers ecosystem.特性CC3220x SimpleLink™ Wi-Fi® Wireless Microcontroller Unit (MCU) System-on-Chip (SoC) is aSingle-Chip With Two Separate Execution Environments: a User Application DedicatedARM®Cortex®-M4 MCU and a Network Processor MCUto Run All Wi-Fi and Internet Logical LayersChip-Level,Wi-Fi Alliance Wi-Fi CERTIFIED Applications Microcontroller SubsystemARM Cortex-M4 Core at 80 MHz Embedded MemoryThe CC3220R and CC3220S Variants Include 256KB of RAMThe CC3220SF Variant is a Flash-Based Wireless MCU With Integrated 1MB of Flash and 256KB of RAM External Serial FlashMcASP Supports Two I2S ChannelsSD SPI I2C UART 8-Bit Parallel Camera Four General-Purpose Timers With 16-Bit PWM Mode Watchdog Timer 4-Channel 12-Bit ADCs Up to 27 GPIO Pins Debug Interfaces: JTAG, cJTAG, SWDWi-Fi Network Processor (NWP)SubsystemWi-Fi Internet-on-a-chip Dedicated ARM 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 and Group OwnerWPA2 Personal and Enterprise Security: WEP, WPA/WPA2 PSK, WPA2 Enterprise (802.1x) IPv4 and IPv6 TCP/IP Stack Industry-Standard BSD Socket Application Programming Interfaces (APIs) 16 Simultaneous TCP or UDP Sockets 6 Simultaneous TLS and SSL SocketsIP Addressing: Static IP, LLA, DHCPv4, DHCPv6 With DAD SimpleLink Connection Manager for Autonomous and Fast Wi-Fi Connections Flexible Wi-Fi Provisioning With SmartConfig Technology, AP Mode, and WPS2 OptionsRESTful API Support Using the Internal HTTP Server Embedded Network Applications Running on Dedicated Network Processor Wide Set of Security Features:Hardware Features:Separate Execution Environments Device Identity Hardware Crypto Enginefor Advanced Fast Security, Including: AES, DES, 3DES, SHA2, MD5, CRC, andChecksum Initial Secure Programming: Debug Security JTAG and Debug Ports are Locked Personal andEnterprise Wi-Fi Security Secure Sockets (SSLv3,TLS1.0/1.1/TLS1.2)Networking SecurityPersonal and Enterprise Wi-Fi Security Secure Sockets (SSLv3, TLS1.0, TLS1.1, TLS1.2) HTTPS Server Trusted Root-Certificate Catalog TIRoot-of-Trust Public keySW IP Protection Secure Key StorageFile System Security Software TamperDetection Cloning Protection Secure Boot: Validate the Integrity and Authenticity of the Runtime BinaryDuring BootEmbedded Network Applications Running on the Dedicated Network ProcessorHTTP/HTTPS Web Server With Dynamic User CallbacksmDNS, DNS-SD, DHCP Server PingRecovery Mechanism—Can Recover to Factory Defaults or to a Complete Factory Image Wi-Fi TX Power18.0 dBm @ 1 DSSS 14.5 dBm @ 54 OFDMWi-Fi RX Sensitivity–96 dBm @ 1 DSSS–74.5 dBm @ 54 OFDMApplication 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): 135 µA (Measured on CC3220R, CC3220S, and CC3220SF With 256-KB RAM Retention) RX Traffic (MCU Active): 59 mA (Measured on CC3220R and CC3220S; CC3220SF Consumes an Additional 10 mA) @ 54 OFDM TX Traffic (MCU Active): 223 mA (Measured on CC3220R and CC3220S; CC3220SF Consumes an Additional 15 mA) @ 54 OFDM, Maximum Power Idle Connected (MCU in LPDS): 710 µA (Measured on CC3220R and CC3220S With 256-KB RAM Retention) @ DTIM = 1Clock Source40.0-MHz Crystal With Internal Oscillator32.768-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.
