Add Wi-Fi® to low-cost, low-power MCU for IoT applications. The CC3120MOD is an FCC, IC, CE, MIC, SRRC, and Wi-Fi CERTIFIED™ module that is part of the SimpleLink™ Wi-Fi family, which dramatically simplifies the implementation of Internet connectivity. The CC3120MOD integrates all protocols for Wi-Fi and Internet, which greatly minimize host MCU software requirements. With built-in security protocols, the CC3120MOD solution provides a robust and simple security experience. Additionally, the CC3120MOD 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 CC3120MOD is available in an LGA package that is easy to lay out with all required components including serial Flash, RF filter, crystal, and passive components that are fully integrated.

The Wi-Fi network processor subsystem features Wi-Fi Internet-on-a chip™ circuitry and contains an additional dedicated Arm® MCU that off-loads many of the networking activities from the host MCU. This 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. The CC3120MOD module supports station, access point, and Wi-Fi direct modes. The module supports WPA2 personal and enterprise security and WPA3 personal and enterprise security. This subsystem includes embedded TCP/IP, TLS/SSL stacks, an HTTP server, and multiple Internet protocols. The CC3120MOD module supports a variety of Wi-Fi provisioning methods, including HTTP based on AP mode, SmartConfig™ technology, and WPS2.0.

As part of TI’s SimpleLink Wi-Fi family second generation, the CC3120MOD module introduces the new features and enhanced capabilities, such as the following:

  • IPv6
  • Enhanced Wi-Fi provisioning
  • Optimized low-power management
  • Wi-Fi AP connection with up to four stations
  • More concurrently opened BSD sockets and up to 16 BSD sockets, of which 6 are secure
  • HTTPS support
  • RESTful API support
  • Asymmetric keys
  • Crypto library

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 and shutdown, which requires approximately 5 µA and 1 µA, respectively. The CC3120MOD module is delivered with a slim and user-friendly host driver to simplify the integration and development of network applications. The host driver can easily be ported to most platforms and operating systems (OS). It is written in strict ANSI-C (C99) and requires minimal platform adaptation layer (porting layer). The CC3120MOD 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 for a TCP client application.

The CC3120MOD module is part of the SimpleLink™ microcontroller (MCU) platform which consists of Wi-Fi, Bluetooth® low energy, Sub-1 GHz, and host MCUs, which all share a common, easy-to-use development environment with a single core software development kit (SDK) and rich tool set. A one-time integration of the SimpleLink platform lets you add any combination of the portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change.

The CC3120MOD modules comes in an easy-to-layout LGA package and is delivered as a complete platform solution including various tools and software, sample applications, user and programming guides, reference designs, and the TI E2E support community. The module family is also part of the SimpleLink MCU portfolio and supports the SimpleLink developers ecosystem. For more information, visit www.ti.com/SimpleLink.
