CES 2018

Chipsets for DSRC-based communication

Published 2018-01-05

Autotalks (Israel) and ST Microelectronics (France) present jointly at CES the Craton2 chipset respectively the Telemaco3 single-chip MCU. CAN FD is one of the interface options for the in-vehicle networks.

DSRC (dedicated short range communication) is the base for many vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-everything (V2X) communication. Autotalks and ST have developed jointly a platform, which is based on the Craton2 chipset and the ARM-based Telemaco3 micro-controller. This platform is ready to go into mass production. The provided DSRC-based technology exceeds all existing US Department of Transportation (USDOT) specifications. "Using the technology we’re highlighting now, DSRC is ready for mass deployment with the ultimate goal of maximizing safety and mobility for both human-driven and autonomous vehicles," said Hagai Zyss, CEO of Autotalks. "Our demonstration with ST is further evidence of the strong V2X ecosystem Autotalks has established in bringing next-generation automotive-qualified solutions to connected and autonomous vehicles today."

“The cooperation with Autotalks is a strong component in delivering on ST’s Smart Driving mission, which combines all of the elements to make automotive systems safer, greener, and more connected,” said Fabio MarchioĢ from ST. “ST’s efforts have contributed to assuring the seamless integration of the Craton2-based V2X module with ST’s advanced technologies for connected cars, including automotive secure processors, GNSS receivers, and sensors.“

Two V2X showcases, one emphasizing the USDOT-compliant, DSRC-based solution and the other, a Virtual Reality experience that allows visitors to “drive” a V2X-equiped vehicle so they can see the technology’s benefits while “driving through” multiple common hazardous road scenarios, are on show by invitation-only.

The Craton2 chipset features CAN FD and Flexray connectivity. In addition, it provides an IEEE 802.11p modem and a V2X hardware security module (eHSM). The integrated single/dual Cortex-A7 processor runs the V2X middleware. Furthermore, the chipset supports IEEE 802.11a/b/g/n/ac to enable external WiFi communication.
