5.3 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 CC3100 device supports station, AP,

and Wi-Fi Direct modes. The device also supports WPA2 personal and enterprise security and WPS 2.0.

The Wi-Fi network processor includes an embedded IPv4 TCP/IP stack.

Table 5-1 summarizes the NWP features.
