The world’s largest supplier of automotive IC (integrated circuit) chipsets, NXP Semiconductors, has expanded its position in secure vehicle-to-everything communications (V2X) with its next-generation RoadLINK system.
NXP’s new SAF5400 is the world’s first automotive-qualified, high-performance, single-chip DSRC (dedicated short-range communications) modem, and forms the core of the secure RoadLINK V2X system platform.
Its unique scalable architecture, new industry-leading security features, and leading edge RFCMOS and software defined radio (SDR) technologies offer OEMs flexible options for cross-regional secure V2X adoption and field upgradeability. Its V2X technology allows vehicles to communicate with other cars, infrastructure and vulnerable road users to increase driver safety and smooth out the autonomous driving experience.
The DSRC/802.11p version of V2X delivers minimum latency for real-time communication and an operating range that exceeds a mile, even in areas where cellular network connections are not available. DSRC also provides dedicated secure safety channel operation to enable the secure communication of safety messages and other data in real time, forming an essential part of the suite of autonomous driving sensors for connected cars and trucks, as well as being instrumental in truck platooning.
The NXP SAF5400 modem integrates advanced transceiver technology plus the full baseband, MAC and firmware into a complete one-chip standalone modem. It provides superior RF performance for industry-leading range under all channel conditions and is the industry’s first single-chip modem with the capability to verify more than 2000 messages per second on chip.
The NXP V2X system platform operates in the 5.9GHz and 760MHz bands and is compatible with global software protocols from all leading vendors, enabling a true global V2X solution. To enable the highest security, NXP provides the SXF1800, a dedicated hardware secure element based on technology used in many of the world’s most sensitive environments, which demonstrates very high resistance to physical probing and tampering.
“We have delivered a secure single chip V2X platform that will enhance a vehicle’s ability to ‘see’ around corners, and will contribute to our efforts to save lives,” said Kurt Sievers, executive vice president and general manager at NXP Automotive.
“The next generation NXP RoadLINK builds on our existing industry leading solution, which is already on the roads of the world, and provides a high-performance platform that is scalable and easy for OEMs to adopt across the globe.”
