41 / 75 page  9 Detailed Description 9.1 Overview Connect any microcontroller (MCU) to the Internet of Things (IoT) with the CC3130 device from Texas Instruments™. The CC3130 Wi-Fi® Internet-on-a chip™ device contains an Arm® Cortex®-M3 MCU dedicated to wi-fi and internet protocols, in order to offload networking activities from the host MCU. The 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 and a built in power management for best in class low power performance. The CC3130 device supports station, AP, and Wi ‑Fi Direct® modes. The device also supports WPA2™ personal and enterprise security, WPS 2.0, and WPA3 personal 4. The Wi-Fi network processor includes an embedded IPv6 and IPv4 TCP/IP stack. 9.2 Device Features 9.2.1 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 band (channels 1 through 13). Note 802.11n is supported only in Wi-Fi® station and Wi-Fi Direct®. • The automatically calibrated 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 device 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 with HTTP server – WPS - Wi-Fi Protected Setup, supporting both push button and pin code options. – SmartConfig™ Technology: TI proprietary, easy to use, one-step, one-time process used to connect a CC3130-enabled device to the home wireless network. • 802.11 transceiver mode allows transmitting and receiving of proprietary data through a socket 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. • Antenna selection for best connection • BLE/2.4 GHz radio coexistence mechanism to avoid interference 4 See CC3x35 SDK v3.40 or newer for details. www.ti.com CC3130 SWRS227 – MARCH 2020 Copyright © 2020 Texas Instruments Incorporated Submit Document Feedback 41 |
