Reliable Wi-Fi 4 Chip Carries Next-Generation WPA3 Security

Nov. 17, 2020
With enough connectivity horsepower for IoT-connected devices like smart lighting, the CYW43439 brings WPA3 security to home automation.

IoT security is a hot topic, and in its CYW43439 Wi-Fi/Bluetooth/BLE combination IC, Infineon Technologies now offers what it says is one of the industry’s only dedicated Wi-Fi 4 solutions to deliver the latest WPA3 security standard. In IoT applications such as smart thermostats and smart lighting, the CYW43439 is expected to make it easier for designers to comply with new security regulations currently emerging worldwide, including the California Consumer Privacy Act. This, for example, gives more privacy rights to consumers, including the right to know about the personal information a business collects, and the right for that information to be deleted.

The bulk of IoT products function effectively with the basic connectivity implemented by Wi-Fi 4; thus, the standard will remain the workhorse of IoT designs for years to come. IoT-connected devices like thermostats and lighting require only low bandwidth and low duty cycles. This means there will be an ongoing need for these devices to support the latest security features, such as WPA3. It allows more robust authentication, increased cryptographic strength, and more resilient mission-critical networks.

With Wi-Fi 4, the CYW43439 offers cross-platform features for RTOS, Linux, and Android, and development support for software that includes advanced smart-coexistence for multi-user Wi-Fi and Bluetooth applications, enabling multiple connections simultaneously including BLE Mesh networking. The devices reduce system power consumption by providing Host SoC off-load processing for network management and audio applications reducing CPU loading. Its optimized software for library-based functions allows connections to mobile devices or any cloud service at any time.

Infineon’s CYW43439 with ModusToolbox software gives designers access to one of the most adaptable development systems for IoT, including carefully packaged solutions supporting popular ecosystems and cloud management tools.

The Infineon CYW43439 is available in volume quantities. Commercial modules are also available from module partners.
