Broadcom Corp. is expanding the opportunity for OEMs to deliver wireless innovation in personal computers, notebooks and netbooks with its BCM43142 InConcert combo chip. According to Broadcom, the new chip combines WiFi Direct connectivity with seamless proximity based pairing, dramatically simplifying wireless connectivity in the home. The combo chip supports a variety of platforms including next-generation Windows and Android-based systems.

The single-die BCM43142 claims to be the industry's first 40nm WiFi Bluetooth Combo Chip for notebooks and netbooks. It provides power savings and coexistence improvements over earlier InConcert PC combo modules of Broadcom. With its high levels of integration, the 40nm device is also said to provide a reduction in footprint, lower bill of materials, and a 40 percent reduction in power consumption, providing a cost effective, compact and high-performance solution for the PC market.

According to an ABI Research study, the demand for single-die Bluetooth and WiFi combo chips will continue to grow by 15 percent CAGR between 2009 and 2015. The study also notes that more than 75 percent of the combined notebooks and netbooks shipments in 2013 will have both Bluetooth and WiFi.

The BCM43142 software development kit includes APIs for Bluetooth Low Energy (BLE), Bluetooth High Speed and 802.11n WiFi Direct functionality. These allow devices to automatically recognize and communicate with each other directly, delivering innovative applications such as proximity-based PC security, router-less collaboration and instant photo/video sharing.

The BCM43142 also provides support for coexistence schemes with additional wireless technologies such as LTE and WiMAX.

According to John DaCosta, director of product marketing, mobile and wireless group of Broadcom, "The future of innovation in consumer electronics is in wireless connectivity. By extending Broadcom's leadership in wireless integration to the 40nm node, we're delivering the most cost effective and industry proven integrated solutions to the PC segment. By leveraging Broadcom's leadership in WiFi Direct and software APIs, Broadcom is enabling PC OEMs to develop and deliver new and compelling solutions to their customers."
