Cypress' Broadcom IoT acquisition yields multi-protocol wireless development platform

November 11, 2016 // By Graham Prophet
Cypress Semiconductor has announced a new version of its development platform for the Internet of Things (IoT) that enables wireless connectivity in minutes. The Wireless Internet Connectivity for Embedded Devices (WICED) Studio 4 platform provides a single development environment for multiple wireless technologies, including Cypress’s Wi-Fi, Bluetooth and combo solutions, with an application programming interface.

The WICED platform supports the most popular cloud services and removes the need for developers to implement the various protocols to connect to them, reducing development time and costs. Cypress believes that many IoT applications will require combination solutions that enable Wi-Fi, Bluetooth and alternative connectivity protocols. The platform embodies – and provides co-existence support tools for – WiFi, ZigBee and Bluetooth protocols, and is, the company says, the only such offering to do so.


The WICED Studio 4 development platform claims the most integrated and interoperable wireless software development kit (SDK) with tested Wi-Fi and Bluetooth protocol stacks, and it offers simplified application programming interfaces that free developers from needing to learn about complex wireless technologies. In line with the IoT trend toward dual-mode connectivity, the kit supports both Cypress’s CYW 43438 Wi-Fi and Bluetooth combination solution and its low-power CYW 20719 Bluetooth and Bluetooth Low Energy (BLE) combination solution, which is now sampling to lead customers. The SDK features a single installer package for multiple wireless technologies with an Eclipse-based Integrated Development Environment (IDE) that runs on multiple operating systems, including Windows, MacOS and Linux. Developers can access the WICED Studio 4 platform, ecosystem and community at


The WICED Studio 4 SDK enables cloud connectivity “in minutes” with its libraries that integrate popular cloud services such as Amazon Web Services, IBM Bluemix, Alibaba Cloud, and Microsoft Azure, along with services from private cloud partners. The SDK provides support for Apple’s HomeKit home automation platform to Apple licensees, and it will soon add support for China’s key Weibo social media platform.


Cypress’s WICED Studio 4 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
