SWRS161 December 2014 CC3100MOD
Completely Offloads Wi-Fi and Internet Protocols from the External Microcontroller
Add Wi-Fi to low-cost, low-power microcontroller (MCU) for Internet of Things (IoT) applications. The CC3100MOD is FCC, IC, CE, and Wi-Fi CERTIFIED module is part of the new SimpleLink Wi-Fi family that dramatically simplifies the implementation of Internet connectivity. The CC3100MOD integrates all protocols for Wi-Fi and Internet, which greatly minimizes host MCU software requirements. With built-in security protocols, the CC3100MOD solution provides a robust and simple security experience. Additionally, the CC3100MOD 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 CC3100MOD is available an LGA package that is easy to lay out with all required components including serial flash, RF filter, crystal, passive components fully integrated.
The Wi-Fi network processor subsystem features a Wi-Fi Internet-on-a-Chip and contains an additional dedicated ARM MCU that completely off-loads 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 CC3100MOD module supports Station, Access Point, and Wi-Fi Direct modes. The module 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 an integrated DC-DC converter with support for a wide range of supply voltages. This subsystem enables low-power consumption modes such as hibernate with RTC mode, which requires approximately 7 μA of current. The CC3100MOD module 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 of less than 7KB of code memory and 700B of RAM memory for a TCP client application.
