TI公司的CC3100是SimpleLink? Wi-Fi網(wǎng)絡(luò)處理器,可以連接任何低成本低功耗的MCU到物聯(lián)網(wǎng)(IoT).器件集成了Wi-Fi和互聯(lián)網(wǎng)所有的協(xié)議,從而大大減少了主MCU的軟件要求.CC3100提供了完整的解決方案平臺,包括各種工具和軟件,應(yīng)用案例,用戶和編程指南,參考設(shè)計和E2E支持社區(qū).本文介紹了CC3100主要特性,硬件框圖和軟件框圖,SimpleLink Wi-Fi解決方案功能框圖和應(yīng)用電路,以及電動汽車服務(wù)裝備(EVSE)加裝Wi-Fi功能參考設(shè)計TIDC-EVSE-WIFI主要特性,電路圖,材料清單和PCB設(shè)計圖.
The CC3100 device is the industry’s first Wi-Fi CERTIFIED chip used in the wireless networking solution. The CC3100 device is part of the new SimpleLink Wi-Fi family that dramatically simplifies the implementation of Internet connectivity. The CC3100 device integrates all protocols for Wi-Fi and Internet, which greatly minimizes host MCU software requirements. With built-in security protocols, the CC3100 solution provides a robust and simple security experience. Additionally, the CC3100 device is a complete platform solution including various tools and software, sample applications, user and programming guides, reference designs and the TI E2E? support community. The CC3100 device is available in an easy-to-layout QFN package.
The Wi-Fi network processor subsystem features a Wi-Fi Internet-on-a-Chip and contains an additional dedicated ARM MCU that completely offloads the host MCU. This subsystem includes an 802.11 b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure Internet connections with 256-bit encryption. The CC3100 device supports Station, Access Point, and Wi-Fi Direct modes. The device also supports WPA2 personal and enterprise security and WPS 2.0. This subsystem includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols.
The power-management subsystem includes integrated DC-DC converters supporting a wide range of supply voltages. This subsystem enables low-power consumption modes, such as the hibernate with RTC mode requiringabout 4 μA of current.
The CC3100 device can connect to any 8, 16, or 32-bit MCU over the SPI or UART Interface. The device driver minimizes the host memory footprint requirements requiring less than 7KB of code memory and 700 B of RAM memory for a TCP client application.
