About AIROC™ Connected MCU

AIROC™ Connected MCUs are single-chip devices that combine Wi-Fi, an MCU, memory and on-chip networking so you can run the application and the connection on one part. Use them to ship cloud-connected products fast without an external host.

 

Why choose it?

  • Self-hosted network stack and drivers on-chip
  • Wi-Fi 4/5, 2.4 and 5 GHz portfolio options
  • Integrated RTOS and TCP/IP to shorten bring-up
  • Small footprint vs. separate MCU + Wi-Fi module
  • Supported in ModusToolbox™ Software with code examples
  • Module options from partners for faster compliance
  • Scales from simple sensors to major appliances

 

AIROC™ Connected MCU portfolio at a glance

Combining Wi-Fi, MCU, and memory on a single chip, AIROC™ Connected MCUs offer a compact, self-hosted solution for cloud connectivity and application processing. With integrated RTOS and networking stacks, these products contain everything needed to get connected and quickly bring advanced products to market.

Our Connected MCU lineup includes Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) supporting both 2.4 GHz and 5 GHz bands.  All Wi-Fi and networking functions are managed on-chip, eliminating the need for an external host to run the network stack.

Infineon’s ModusToolbox™ Software and tools provides code examples and development support for AIROC™ Connected MCUs as well as PSoC™ MCUs and sensors for full-featured IoT applications. Infineon also supports our customers through our global network of IoT partners using production-ready, fully-certified AIROC™ Connected MCU modules.

Certification and validation

Infineon’s AIROC™ Connected MCU solutions meet the rigorous requirements for global regulatory certifications. Our module partners offer pre-certified solutions with integrated antennas, as well as flexible solutions that can be certified at the product level.

Our Connected MCU solutions also meet the requirements for Wi-Fi Alliance system-level certification, providing an extra level of interoperability assurance.

Infineon’s test infrastructure covers interoperability with many of the most popular access points in the market, adding assurance that your end products will operate smoothly in real-world network environments. 

Getting started
  1.  Install ModusToolbox™ Software
    1. Download the installer for your OS (Windows, macOS, Linux) to set up the development environment, including IDE and configurators.
    2. Install base packages for core tools and additional ones for connectivity support.
    3. Verify setup via the Dashboard and configure proxies if needed.
  2. Open the AIROC Connected MCU Examples
    1. Launch Project Creator to select a BSP for your hardware kit and browse Wi-Fi/Connectivity examples.
    2. Import examples from GitHub, such as HTTPS client or OTA updates, which include middleware like MQTT.
    3. Check README for device compatibility (e.g., CYW43xxx chips).
  3. Build and Connect to Your AP, Then Extend with Your Application
    1. Use Device Configurator for peripherals, then build the project with Arm GCC.
    2. Program the device via USB using tools like OpenOCD or KitProg.
    3. Run the example to join a network via serial console and add custom code for sensors or cloud integration.
  4. Review Regulatory and Certification Notes for Your Target Region
    1. Consult product datasheet and module pages for FCC, CE, ISED, MIC/TELEC certifications.
    2. Verify Wi-Fi Alliance compliance and region-specific settings like channel restrictions.
    3. Use pre-certified modules to ease testing.
Frequently Asked Questions

1.   What is an AIROC Connected MCU?
A single-chip part with Wi-Fi, MCU, memory, and on-chip stacks to run both connectivity and your application.

2.   When would I use it instead of a Wi-Fi module plus external MCU?
When you want fewer parts, smaller PCB, and faster bring-up because networking and the app can run on one device.

3.   Which Wi-Fi standards and bands are supported?
Portfolio devices support Wi-Fi 4 or Wi-Fi 5 across 2.4 GHz and 5 GHz; see each product page for specifics.

4.   Do I need an external host?
No. The Wi-Fi and networking stacks run on-chip. You can still pair with another MCU if desired.

5.   What tools support development?
ModusToolbox™ Software with libraries, middleware, and ready examples for AIROC Connected MCUs.

6.   Are pre-certified modules available?

Yes. Partner modules provide integrated antennas and documented regulatory paths. Check each module page for certificates.

7.   How do I assess power and performance?
Use the product datasheet and application notes with measured throughput and current profiles for your use case.

8.   Where can I find certification details?
See the regulatory note on the product page and partner module certificates for your target regions.
