NXP Semiconductors has rolled out the first product from the RoadLINK range aimed at automotive customer design-in. The SAF5100 is a flexible software-defined radio processor for car-to-car (C2C) and car-to-infrastructure (C2I) communication. Scheduled for mass production in 2H14, the SAF5100 is also the first product to become generally available from the MK4 reference design for connected vehicles.

The SAF5100 processor is fully programmable and can support unique algorithms to improve reception in wireless communication. The device can support multiple wireless standards as well as different OEM antenna configurations such as 802.11p antenna diversity, providing OEMs with the flexibility to support emerging standards across multiple regions via firmware updates. It also claims to provide best-in-class wireless link performance via the 802.11p firmware from Cohda Wireless, which is a fully integrated part of the solution. With a 12 x 12mm LFBGA package, the SAF5100 has a very small PCB footprint that allows the 802.11p receiver to fit into confined spaces, and significantly reduces BOM costs. The unique software-defined radio approach allows OEMs to deploy a global C2X solution based on a single hardware platform with end-of-line configurability by firmware download.

NXP's "connected car" technology allows cars to communicate wirelessly with each other and with traffic infrastructure, exchanging data including location, speed and direction. This allows for 360-degree driver awareness to improve road safety by reducing collisions, warning of potential hazards, and avoiding traffics jams.
