The CC3220x 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.
Start your Internet-of-Things (IoT) design with a
Wi-Fi® CERTIFIED® single-chip MCU
System-on-Chip (SoC) with built-in Wi-Fi connectivity. Created for the IoT, the SimpleLink™ CC3220x
device family from Texas Instruments is a single-chip solution,
integrating 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
The CC3220x wireless MCU family is part of the second generation of
TI’s 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
including the following:
Enhanced Wi-Fi provisioning
Enhanced power consumption
Enhanced file system security (supported only by the CC3220S and CC3220SF
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 CC3220x wireless MCU family supports the following modes: station,
AP, and Wi-Fi Direct®. The 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 4.5
µA), 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 4-channel ADC.
The SimpleLink CC3220x device family comes in three different device
variants: CC3220R, CC3220S, and CC3220SF.
The CC3220R and CC3220S devices include 256KB of application-dedicated
embedded RAM for code and data, ROM with external serial flash bootloader, and peripheral drivers.
The CC3220SF device includes application-dedicated 1MB of XIP flash
and 256KB of RAM for code and data, ROM with external serial flash bootloader, and peripheral
drivers. The CC3220S and CC3220SF device options 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 and boot time), and
The CC3220x device family is a complete platform solution including
software, sample applications, tools, user and programming guides, reference designs, and the
E2E™ online community. The device family is also part of the
SimpleLink MCU portfolio and supports the SimpleLink developers ecosystem.
