NXP RoadLink SAF5400 is a Single Chip Secure DSRC/802.11p V2X Platform

Marvell unveiled 88W8987xA wireless SoC for V2X (Vehicle to Everything) applications supporting 802.11p WiFi, and DSRC (Dedicated Short Range Communications) last June, but NXP has recently launched Roadlink SAF5400 which it claims to be the world’s first “automotive qualified, high-performance single-chip DSRC modem”

Key features for Roadlink SAF5400:

  • Compliant with IEEE 802.11p, IEEE 1609.4
  • Compliant with:
    • ETSI EN 302663 – Intelligent Transport Systems (ITS); Access layer specification for Intelligent Transport Systems operating in the 5 GHz frequency band
    • ETSI EN 302571 – Intelligent Transport Systems (ITS); Radiocommunications equipment operating in the 5 855 MHz to 5 925 MHz frequency band; Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive
  • Compliant with ARIB T-109M – 700 MHz Band Intelligent Transport Systems
  • Single channel handling for 802.11p reception/transmission. Includes Channel Switching
  • Optional ECDSA verification: 2000 messages/sec (Brainpool/NIST curves 256 bits)
  • Qualified in accordance with AEC-Q100 grade 2
  • Host interface – SPI, R(G)MII Ethernet, or SDIO

The solution will be used for vehicle to vehicle communication as illustrated below, and potentially other nodes along the road.  Roadlink SAF5400 can be combined with NXP i.MX processor, and security can be achieved by software in the i.MX processor, or via a dedicated SXF1800 hardware secure element based in similar technology used in electronic passports, and banking cards.
