Broadcom Corp. has announced a couple of automotive-grade wireless chips that feature the latest in 5G Wi-Fi and Bluetooth Smart technology. The devices allow car makers and tier one integrators to deliver high-speed connectivity within and beyond the vehicle, providing Internet, cloud applications and entertainment content via telematics or hot spot connections, stated the company.

Broadcom offers the 5G Wi-Fi/Bluetooth Smart 2X2 MIMO combo chip with Real Simultaneous Dual Band (RSDB) support as well as a stand-alone tri-mode Bluetooth Smart (version 4.2) SoC. Optimised to meet the rigorous standards of the automotive industry, all products have been tested to AECQ100 automotive environmental stress requirements, are manufactured in TS16949 certified facilities and offer full production part approval process (PPAP) support.

The BCM89359 5G Wi-Fi/Bluetooth Smart 2X2 MIMO Combo Chip with RSDB Support is optimised for seamless interaction with enhanced wireless applications and feature-rich systems such as Apple CarPlay and Google Auto Link, and is architected specifically for multi-band concurrent automotive infotainment and telematics operation. The RSDB support enables simultaneous connectivity to the 5GHz and 2.4GHz bands, improving throughput and latency when using multiple applications. In addition, the integrated 5G Wi-Fi technology provides the bandwidth required for multiple high resolution in-car displays, allowing uncongested 5GHz video to coexist concurrently with Wi-Fi Internet access and 2.4GHz Bluetooth hands-free audio.

The 2x2 MIMO technology claims to deliver twice the Wi-Fi performance of any other solution on the market today, providing the highest throughput in-car network possible for multiple user experiences, stated the company. Likewise a dedicated Bluetooth antenna enables concurrent operation of Bluetooth and WLAN applications and employs advanced coexistence algorithms to maximise voice quality and data access speed in simultaneous operation.

The BCM89072 Tri-mode Bluetooth Smart v4.2 SoC offers Bluetooth HCI, Bluetooth embedded stack and Bluetooth Smart functional modes of operation in a monolithic, single-chip design. Integrating a Class 1 transceiver, baseband processor, ARM Cortex M3 and application memory on a single die allows the replacement of function-specific devices with a single device that offers all Bluetooth modes of operation, noted the company.

Featuring the latest in Bluetooth Smart technology (Bluetooth Low Energy), the BCM89072 SoC enables seamless connectivity between the car and passenger wearable tech to monitor biometric indicators including driver fatigue, blood alcohol content and glucose levels. Integrated direction finding capability enables future angle of arrival based V2X applications while supporting a wide spectrum of existing applications including smart remotes, tire pressure monitoring and hands free communication, the company added.

The BCM89359 and BCM89072 reference boards are available.
