Wi-Fi + Bluetooth 5 + 802.11p for V2X and infotainment
This wireless combo chip supplies in-car Wi-Fi, Bluetooth 5 and 802.11p and is Marvell’s fourth generation family of wireless SoCs enabling advanced infotainment, telematics and Wi-Fi gateways for the connected car. Its features are tailored around the automotive market and it meets AEC-Q100 grade 2 standards.
The 88W8987xA family of wireless products complements Marvell’s 88Q2112 automotive Ethernet physical layer (PHY) transceiver to provide a complete wired and wireless connectivity solution for the connected car. The 88Q2112 enables 1000BASE-T1 gigabit Ethernet over a single twisted pair copper cable, suiting it for distributing HD video, audio and voice for advanced driver assistance systems (ADAS) and IVI applications.
In addition to supporting the growing needs of IVI and emerging screen projection technologies, the 88W8987xA’s 802.11p features will enable a new era of safety and autonomous driving by supporting pending National Highway Traffic Safety Administration (NHTSA)/Federal Motor Vehicle Safety Standards (FMVSS) and Dedicated Short Range Communication (DSRC) requirements. The 88W8987xA is also the first wireless combo solution supporting Bluetooth 5 including Bluetooth Low Energy Angle of Arrival and Departure (AoA/AoD) and 802.11mc which will enable new use-models for car makers with wearables and phones to support new access, personalization and car location services.
The 88W8987xA provides flexibility for system design and is interoperable with a wide selection of host SoCs, hardware HSMs, WAVE (1609.x) stacks and operating systems. 88W8987xA drivers are available for the Android platform, Linux and QNX.
