Start your design with the fully programmable FCC, IC, CE, and Wi-Fi Certified wireless
microcontroller (MCU) module with built-in Wi-Fi connectivity. Created for the IoT, the SimpleLink
CC3220MODx module family
from Texas Instruments™ is a wireless module that integrates two
physically separated on-chip MCUs.
- An application processor – ARM Cortex-M4 MCU with a
user-dedicated 256KB of RAM, and an optional 1MB of XIP Flash.
- 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.
wireless MCU family is part of the second generation of TIs Internet-on-a-chip family of
solutions. This generation introduces new features and capabilities that further simplify the
connectivity of things to the internet. The new capabilities include:
- 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)
- HTTPS support
- RESTful API
- Asymmetric keys crypto library
The CC3220MODx wireless MCU family supports the following modes:
station, AP, and Wi-Fi Direct. The CC3220MODx device also supports WPA2 personal and enterprise
security. This subsystem includes embedded TCP/IP and TLS/SSL stacks, HTTP server, and multiple
Internet protocols. The device 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 7µA), and shutdown mode
(consuming only 1 µA).
The device 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 device family comes in two different device variants:
CC3220MODS and CC3220MODSF.
- The CC3220MODS device includes 256KB on
application-dedicated embedded RAM for code and data.
CC3220MODSF device includes application-dedicated 1MB of XIP Flash and 256KB of RAM for code and
Both devices integrate the 40-MHz crystal, 32.768-kHz RTC clock, 32-Mb SPI serial
Flash, RF filter, and passive components. The devices 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 device is part of the SimpleLink microcontroller (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 device 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, visit
