Start your design with the fully programmable FCC, IC, CE, MIC, and SRRC Certified
wireless microcontroller (MCU) module with built-in Wi-Fi connectivity. Created for the IoT, the
SimpleLink™ CC3220MODx and CC3220MODAx module family from Texas
Instruments™ is a wireless module that integrates two physically separated on-chip
- An application processor—Arm®
Cortex®-M4 MCU with a user-dedicated 256KB of RAM, with 1MB of XIP Flash
available on the CC3220SF variant.
- A network processor MCU
to run all Wi-Fi® and Internet logical layers. This ROM-based 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 CC3220MODx and CC3220MODAx wireless MCU family is a part of the second generation
of the Internet-on-a chip™ family of solutions from TI. This generation introduces new features and
capabilities that further simplify the connectivity of things to the internet. The new capabilities
- Optimized low-power
- Enhanced file-system
- Wi-Fi AP connection with up to four
- More concurrently opened BSD sockets—up to 16 BSD
sockets (6 are secure HTTPS support)
- RESTful API support
- Asymmetric keys crypto library
The CC3220MODx and CC3220MODAx wireless MCU family supports the
following modes: station, AP, and Wi-Fi Direct®. The CC3220MODx and
CC3220MODAx modules also supports WPA2 personal and enterprise security. This subsystem includes
embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple Internet protocols. The module
supports a variety of Wi-Fi provisioning methods, including HTTP based on AP mode, SmartConfig™
technology, and WPS2.0.
The power-management subsystem includes integrated DC/DC converters that support a wide
range of supply voltages. This subsystem enables low-power consumption modes for extended battery
life, such as low-power deep sleep, hibernate with RTC (consuming only 5 µA), and shutdown mode
The module includes a wide variety of peripherals, including a fast parallel camera
interface, I2S, SD, UART, SPI, I2C, and a 4-channel ADC.
The SimpleLink CC3220MODx and CC3220MODAx module family come in four different module
variants: CC3220MODS, CC3220MODSF, CC3220MODA, and CC3220MODASF.
- The CC3220MODS and CC3220MODAS modules include 256KB on
application-dedicated embedded RAM for code and data. In addition, the CC3220MODAS includes an
- The CC3220MODSF and CC3220MODASF modules
include application-dedicated 1MB of Serial Flash and 256KB of RAM for code and data. In addition,
the CC3220MODASF includes an integral antenna.
The four modules integrate the 40-MHz crystal, 32.768-kHz RTC clock, 32-Mb SPI serial
Flash, RF filter, and passive components. The modules also have additional security features, such
as encrypted and authenticated file systems, user IP encryption and authentication, secured boot
(authentication and integrity validation of the application image at Flash boot time), and
The CC3220MODx and CC3220MODAx devices are a part of the SimpleLink™ MCU platform,
which consists of Wi-Fi, Bluetooth® low energy, Sub-1 GHz, and host MCUs. 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
devices from the portfolio into your design. The ultimate goal of the SimpleLink platform is to
achieve 100 percent code reuse when your design requirements change.
The CC3220MODx and CC3220MODAx module family is a complete platform solution including
software, sample applications, tools, user and programming guides, reference designs, and the
E2E™ online community. The module family is also part of the
SimpleLink™ MCU portfolio and supports the SimpleLink™ developers ecosystem. For more information,
