For some time now, consumers have been looking to their cars to provide access to information and entertainment options. While Bluetooth and Wi-Fi have been widely deployed in vehicles for infotainment applications, automotive wireless communication is becoming so much more. Enabling telematics, Wi-Fi gateways and V2V/ V2I connections for the connected car, keyless entry and vehicle location, connectivity is going beyond entertainment.
Marvell is enabling constant connectivity in the car with a complete product portfolio of AEC-Q100 qualified wireless automotive connectivity solutions.
The 88W8987xA Family
The Marvell® 88W8987xA family of automotive wireless SoCs is a highly integrated IEEE 802.11ac(wave2)/ IEEE 802.11p transceiver and Bluetooth 5 single-chip foot print compatible combo solution, specifically designed to support the speed, reliability, and quality requirements of 1609.x/Wireless Access in Vehicular Environments (WAVE)/Dedicated Short Range Communications (DSRC) systems, In-vehicle Infotainment systems and secure wireless Gateway systems. It also supports Wireless Location Services (WLS) via its support of technologies like 802.11mc and BLE AoA/AoD opening several new use cases in automotive.
The Marvell 88W8897 system-on-a-chip (SoC) is the industry’s first 802.11ac chip to combine Bluetooth 4.2, mobile MIMO, transmit beamforming, and built-in support for for all screen projection technologies gaining momentum in automotive. It continues to support multiple Wi-Fi interfaces via Marvell’s innovative virtual dual-MAC architecture. It supports 2 or 3 antenna configurations giving system designers the ultimate flexibility in their design of IVI, Telematics or wireless Gateway solutions.
The Marvell Avastar 88W887 builds on top of the feature-rich and robust software architecture of earlier generations of Marvell’s automotive-grade products and provides a seamless upgrade path to cutting-edge technologies, such as 11ac 1X1 VHT for support of all screen projection technologies gaining momentum in automotive. A virtual dual-MAC implementation allows for support of these demanding use cases even when multiple wireless interfaces are required giving system designers ultimate flexibility.
