Add Wi-Fi® to low-cost, low-power MCU for IoT applications.
The CC3120MOD is an FCC, IC, TELEC, China, CE, and Wi-Fi CERTIFIED™ module that is part of the new
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 a Wi-Fi Internet-on-a-chip and contains
an additional dedicated ARM MCU that off-loads many of the networking
activities from 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 CC3120MOD module supports
station, access point, and Wi-Fi direct modes. The module supports WPA2 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
- Optimized low-power
- Wi-Fi AP connection with up to four
- More concurrently opened BSD sockets and up to 16
BSD sockets, of which 6 are secure
- RESTful API support
- Asymmetric keys
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
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 device 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 enables you to add any combination
of the portfolio’s devices into your design, allowing 100 percent code reuse when your design
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.
