6.3 Wi-Fi^® Network Processor Subsystem
The Wi-Fi network processor subsystem includes a dedicated ARM MCU to completely offload the host
MCU along with an 802.11 b/g/n radio, baseband, and MAC with a powerful crypto engine for a fast,
secure WLAN and Internet connections with 256-bit encryption. The CC3220MODx and CC3220MODAx
modules support station, AP, and Wi-Fi Direct modes. The module also supports WPA2 personal and
enterprise security and WPS 2.0. The Wi-Fi network processor includes an embedded IPv6, IPv4 TCP/IP
stack.
6.3.1 WLAN
The WLAN features are as follows:
• 802.11b/g/n integrated radio, modem, and MAC supporting WLAN communication as a BSS station,
AP, Wi-Fi Direct client and group owner with CCK and OFDM rates in the 2.4-GHz ISM band, channels
1 to 13.
NOTE
802.11n is supported only in Wi-Fi station, Wi-Fi direct, and P2P client modes.
• Autocalibrated radio with a single-ended 50-Ω interface enables easy connection to the antenna
without requiring expertise in radio circuit design.
• Advanced connection manager with multiple user-configurable profiles stored in serial-Flash allows
automatic fast connection to an access point without user or host intervention.
• Supports all common Wi-Fi security modes for personal and enterprise networks with on-chip security
accelerators, including: WEP, WPA/WPA2 PSK, WPA2 Enterprise (802.1x).
• Smart provisioning options deeply integrated within the module providing a comprehensive end-to-end
solution. With elaborate events notification to the host, enabling the application to control the
provisioning decision flow. The wide variety of Wi-Fi provisioning methods include:
– Access Point using HTTPS
– SmartConfig Technology: a 1-step, 1-time process to connect a CC3220MODx or CC3220MODAx-
enabled module to the home wireless network, removing dependency on the I/O capabilities of the
host MCU; thus, it is usable by deeply embedded applications
• 802.11 transceiver mode allows transmitting and receiving of proprietary data through a socket without
adding MAC or PHY headers. The 802.11 transceiver mode provides the option to select the working
channel, rate, and transmitted power. The receiver mode works with the filtering options.
6.3.2 Network Stack
The Network Stack features are as follows:
• Integrated IPv4, IPv6 TCP/IP stack with BSD socket APIs for simple Internet connectivity with any
MCU, microprocessor, or ASIC
Not all BSD APIs are supported.
NOTE
• Support of 16 simultaneous TCP, UDP, or RAW sockets
• Support of 6 simultaneous SSL\TLS sockets
• Built-in network protocols:
– Static IP, LLA, DHCPv4, DHCPv6 with DAD and stateless autoconfiguration
– ARP, ICMPv4, IGMP, ICMPv6, MLD, ND
– DNS client for easy connection to the local network and the Internet
