The CC3120MODRNMMOBR low-cost, low-power MCU for IoT applications adds Wi-Fi®. The CC3120MOD is an FCC, IC, CE, MIC, SRRC, and Wi-Fi CERTIFIED™ module from the SimpleLink™ Wi-Fi family that greatly simplifies the implementation of Internet connectivity. The CC3120MOD integrates all protocols for Wi-Fi and Internet, greatly reducing the 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 tools and software, sample applications, user and programming guides, reference designs, and the TI E2E™ support community. The CC3120MOD is housed in an LGA package for easy placement of all necessary components including serial flash memory, RF filters, crystals and fully integrated passives.

The Wi-Fi network processor subsystem features Wi-Fi Internet-on-a chip™ circuitry and includes an additional dedicated Arm MCU to reduce networking activity from the host MCU. This subsystem includes an 802.11b/g/n radio, baseband, and MAC with a powerful encryption engine with 256-bit encryption for fast, secure Internet connections. The CC3120MOD module supports base station, access point, and Wi-Fi Direct modes. This module supports WPA2 Personal and Enterprise security, and WPA3 Personal and Enterprise security. This subsystem contains embedded TCP/IP, TLS/SSL stack, HTTP server, and multiple Internet protocols. The CC3120MOD module supports various Wi-Fi configuration methods including HTTP over AP mode, SmartConfig™ technology and WPS2.0.

The CC3120MOD module is part of TI's second-generation SimpleLink Wi-Fi family with new features and enhancements such as:

IPv6

Enhanced Wi-Fi configuration

Optimized Low Power Management

Wi-Fi AP can connect up to 4 base stations

More BSD sockets and up to 16 BSD sockets (6 of which support secureHTTPS)

Support for RESTful APIs

asymmetric key

encryption library

The power management subsystem includes an integrated DC/DC converter that supports a wide supply voltage range. The subsystem supports low-power modes such as RTC sleep and shutdown modes, which require approximately 10000 Ω of current. Requiring 5µA and 1µA of current, respectively. The CC3120MOD module comes with a user-friendly host driver with a small footprint, which simplifies the integration and development of network applications. Host drivers are easily portable to most platforms and operating systems (OS). Written in strict ANSI-C (C99) standard, requires minimal platform adaptation layer (porting layer). The CC3120MOD module can interface to any 8-bit, 16-bit or 32-bit MCU through SPI or UART interface. The device driver minimizes host memory footprint requirements, requiring less than 7KB of code memory and 700B of RAM for a TCP client application.
