NXP launches ‘world’s first’ scalable, single-chip secure vehicle-to-x platform


NXP Semiconductors, one of the world’s largest suppliers of automotive semiconductor solutions, has has launched its secure next generation RoadLink vehicle-to-everything communications solution.

The new NXP SAF5400 is the “world’s first automotive qualified, high-performance single-chip DSRC modem”, claims the company.

Its “unique scalable architecture”, new security features, and RF CMOS and software defined radio technologies offer original equipment manufacturers with flexible options for cross-regional secure V2X adoption and field upgradeability, says NXP. 

Vehicle-to-everything, or V2X, technology allows vehicles to communicate with other cars, infrastructure and 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 one 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 today’s connected cars and trucks.

V2X based on DSRC is also instrumental in truck platooning, a forerunner of future eco-friendly driving scenarios.

The NXP SAF5400 modem integrates advanced transceiver technology plus the full baseband, MAC and firmware into a complete one-chip standalone modem.

NXP claims 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 SAF5400 architecture is fully scalable to enable its combination with application processors such as NXP’s i.MX family, security, power management and in-vehicle networking solutions, all offered as part of the NXP secure V2X system platform.

To enable the highest security, NXP provides the SXF1800, a dedicated hardware secure element based on technology used today in many of the world’s most sensitive security environments from electronic passports, banking cards, smartphones and now automobiles.

Confirmed by third party security evaluations and certifications, the SXF1800 demonstrates very high resistance to physical probing and tampering.

V2X security requirements can also be met with software functions on NXP’s i.MX processors, offering customers a performance / cost trade-off choice.

The secure single-chip V2X solution incorporates NXP’s software defined radio technology which provides customers with a platform that supports different regional standards with a single hardware solution.

This integration reduces development, qualification and maintenance efforts significantly and eases the challenges of global V2X rollouts.

The ultra-compact, one-chip integration of analog RF with digital baseband processing into a single chip leverages NXP’s RFCMOS technology for a smaller hardware footprint.

Kurt Sievers, executive vice president and general manager, NXP Automotive, says: “NXP has 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.

“The next generation NXP RoadLINK™ builds on NXP’s 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.”

The NXP V2X system platform operates in the 5.9 GHz and 760 MHz bands and is compatible with global software protocols from all leading vendors, enabling a true global V2X solution.

The platform meets and exceeds the current guidelines of the US DOT’s Notice of Proposed Rulemaking, as well as emerging standards in Europe, Japan and Korea.

The NXP SAF5400 single-chip modem is the core of the secure V2X system platform called RoadLink.

RoadLink is the V2X solution has completed more than 1 million test days to date and is the only 5.9 GHz V2X system solution proven in volume production today, claims NXP.
