Wi-Fi + Bluetooth ‘combo’ with integrated USB simplifies wireless enablement
The highly integrated Cypress CYW4373 incorporates a USB 2.0 hub that provides a common WLAN and Bluetooth interface. The combination product is suitable for smart home products and network peripherals such as home appliances and printers.
Wi-Fi networks powered by 802.11ac simultaneously deliver low-latency and high-speed with secure device authentication, suiting its use as a wireless technology to connect directly to the cloud. Cypress’ 802.11ac solutions use high-speed transmissions to enable IoT devices with faster downloads and better range, as well as lower power consumption by quickly exploiting deep sleep modes. The CYW4373 solution is supported in Cypress’ WICED Studio IoT development platform, which manages the integration of wireless technologies for developers.
Cypress adds, “Cypress’ 802.11ac combo solutions enable coexistence with Bluetooth in the crowded 2.4-GHz band, providing audio, video and voice control applications with high fidelity, even in multi-user environments.”
The CYW4373 combo solution features a dual-band 2.4- and 5-GHz radio with dynamic channel selection of 20-, 40- and 80-MHz channels, supporting up to 433 Mbps performance, and it includes a separate Bluetooth/BLE 4.2 subsystem. The product simplifies system design with a common USB hub or shared SDIO interface to the system host controller.

The Cypress WICED Studio IoT development platform features an integrated and interoperable wireless software development kit (SDK). The SDK includes tested Wi-Fi and Bluetooth protocol stacks, as well as simplified application programming interfaces that free developers from needing to learn complex wireless technologies. The SDK supports Cypress’ Wi-Fi and Bluetooth combination solutions and its Bluetooth and Bluetooth Low Energy devices and enables cloud connectivity with services such as Amazon Web Services, IBM Bluemix, Alibaba Cloud, and Microsoft Azure, along with services from private cloud partners. Cypress’ WICED Studio connectivity suite is microcontroller (MCU)-agnostic and provides support for a variety of third-party MCUs to address the needs of complex IoT applications. The platform also enables cost efficient solutions for simple IoT applications by integrating MCU functionality into the connectivity device. Wi-Fi and Bluetooth protocol stacks can run transparently on a host MCU or in embedded mode, allowing for flexible platform architectures with common firmware.
