The CC3120R device is part of the SimpleLink™ microcontroller (MCU)
platform which consists of Wi-Fi, 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:
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
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).
The CC3120R device comes in an easy-to-layout VQFN 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 CC3120R device is part of the SimpleLink MCU
