1.3 Description
The CC3120R 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 requirements change. For more information, visit
Overview for SimpleLink™ solutions.
Connect any microcontroller (MCU) to the Internet of Things (IoT) cloud with the CC3120R device from
Texas Instruments™. The Wi-Fi^® Alliance CERTIFIED^® CC3120R device is part of the second generation
of the SimpleLink™ Wi-Fi family that dramatically simplifies the implementation of low-power Internet
connectivity.
The CC3120R has all of the Wi-Fi and Internet protocols implemented in the ROM, which runs from the
dedicated on-chip ARM^® network processor and significantly offloads the host MCU and simplifies the
system integration.
The CC3120R Wi-Fi Internet-on-a chip™ device contains a dedicated ARM MCU that offloads 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
CC3120R device supports station, AP, and Wi-Fi direct modes. The device also supports WPA2 personal
and enterprise security. The device includes embedded TCP/IP and TLS/SSL stacks, an HTTP server,
and multiple Internet protocols. The CC3120R device 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 CC3120R device introduces the new
features and enhanced capabilities, such as the following:
IPv6
Enhanced Wi-Fi provisioning
Enhanced power consumption
Wi-Fi AP connection with up to four stations
More concurrently opened BSD sockets; up to 16 BSD sockets, of which 6 are secure
HTTPS support
RESTful API support
Asymmetric keys crypto library
The CC3120R device is delivered with a slim and user-friendly host driver to simplify the integration and
development of networking applications. The host driver can easily be ported to most platforms and
operating systems (OS). The driver is written in strict ANSI-C (C89) and requires minimal platform
adaptation layer (porting layer). The driver has a small memory footprint and can run on 8-, 16-, or 32-bit
microcontrollers with any clock speed (no performance or real-time dependency).
