Automotive wireless ICs target in-vehicle connectivity
The chips deliver high-speed connectivity within and beyond the vehicle, providing Internet, cloud applications, and entertainment content via telematics or hot spot connections. The BCM89359 is a 5G Wi-Fi/Bluetooth Smart 2X2 MIMO combo chip with Real Simultaneous Dual Band (RSDB) support, while the BCM89072 is a stand-alone tri-mode Bluetooth Smart (version 4.2) system-on-a-chip.
Designed to meet automotive industry standards, the 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. Optimized for seamless interaction with enhanced wireless applications and feature-rich systems like Apple CarPlay and Google Auto Link, the BCM89359 WLAN combo device is architected specifically for multi-band concurrent automotive infotainment and telematics operation. RSDB support enables simultaneous connectivity to the 5-GHz and 2.4-GHz bands, improving throughput and latency when using multiple applications.
Integrated 5G Wi-Fi technology provides the bandwidth required for multiple high-resolution in-car displays, allowing uncongested 5-GHz video to coexist concurrently with Wi-Fi Internet access and 2.4-GHz Bluetooth hands-free audio, while 2×2 MIMO technology provides the highest throughput in-car network possible for multiple user experiences. Further, a dedicated Bluetooth antenna enables concurrent operation of Bluetooth and WLAN applications and employs advanced coexistence algorithms to maximize 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.
Featuring the latest in Bluetooth Smart technology (also known as 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.
At the heart of the connected car are the semiconductor chips that make connectivity possible. As the development cycle quickens, analysts predict that the number of chips used in vehicles will rise at a dramatic pace. According to recent analyst data from Strategy Analytics, there could be nearly 1,000 chips per vehicle by 2020.
"Car connectivity is becoming the new battleground for product differentiation in the highly competitive automotive market," said Strategy Analytics’ Richard Robinson, Automotive Communications and Multimedia Service Director. "By combining the same technology associated with the fast-moving mobile and IoT ecosystem with the stringent requirements of the automotive industry, Broadcom is well positioned to strongly compete in the rapidly growing automotive IC market."
The BCM89359 and BCM89072 reference boards are available today.
