NXP’s Newest Modem Gets V2X Up and Running

Secure vehicle-to-everything communication requires hardware like the SAF5400 single chip DSRC modem.

Secure vehicle-to-everything communication (V2X) incorporates V2I (Vehicle-to-Infrastructure), V2V (Vehicle-to-vehicle), V2P (Vehicle-to-Pedestrian), V2D (Vehicle-to-Device) and V2G (Vehicle-to-Grid). Wireless communication ties all these together. Having suitable hardware is critical to V2X operation as well as applications such as truck platooning.

NXP’s latest SAF5400 single-chip, Dedicated Short Range Communications (DSRC) modem is part of NXP’s next generation RoadLINK solution that targets V2X (see figure). It is designed to be paired with NXP’s i.MX platforms. The RFCMOS-based hardware is based around software defined radio (SDR) technologies. It supports dual antenna implementations.

NXP’s SAF5400 single-chip, Dedicated Short Range Communications (DSRC) modem uses a software defined radio.


The SAF5400 supports the IEEE 802.11p standard for wireless access in vehicular environments (WAVE). It uses the licensed ITS band of 5.9 GHz. It is designed to operate at over a one-mile range with low latency. DSRC is designed to provide a dedicated secure safety channel for secure communication of safety messages and transportation data in real time. It is designed to deliver more than 2,000 Basic Safety Message (BSM) verifications per second. The chip includes the full baseband, MAC, firmware, and processor.

The system supports secure boot. It is also designed to work with NXP’s SXF1800 secure element, designed to deliver the security support that has been confirmed by third-party security evaluations and certifications.

The chip is qualified in accordance with AEC-Q100 grade 2. It is Compliant with ETSI EN 302663, ETSI EN 302571, and ARIB T-109M.
