Global V2X Communication Processor

CRATON2, Autotalks second-generation chipset specifically designed for connected autonomous vehicles, is the most advanced and secure, and the only Global V2X communication solution. It integrates a mobility optimized IEEE802.11p DSRC and C-V2X direct communications (PC5) modems, ultra-low-latency V2X Hardware Security Module (eHSM), powerful hardware acceleration engines for line-rate message verification, dual ARM Cortex A7 processor capable of running full V2X middleware and applications and optional secure CAN MCU. In addition, CRATON2 supports IEEE 802.11a/b/g/n/ac to enable external vehicle Wi-Fi for value-added services. Due to its high level of integration, CRATON2 is cost optimized, as it reduces development, integration and certification effort and ensures the quickest time-to-market.
