MediaTek, a global fabless semiconductor company that enables 1.5 billion connected devices a year, and Autotalks, a world leader in V2X (Vehicle to Everything) communication solutions, are cooperating on integrating V2X and telematics.

As part of the cooperation, the two companies have completed a joint reference design for Telematics Control Unit (TCU) integrated with a global V2X chipset. The reference design is based on Autotalks’ global V2X chipset and MediaTek’s newest technology, an automotive-grade cellular modem SoC, enabling a secure, robust and cost-effective global TCU architecture.

The joint design can serve as a reference to car-makers and Tier-1s for an optimal, cybersecure and flexible telematics unit integrated with physically isolated global V2X chipset to ensure domain separation between safety (V2X) and Telematics (Vehicle to Network - V2N) domains.

In terms of technological versatility, Autotalks’ and MediaTek’s solution is global and offers a single configurable platform supporting both DSRC and C-V2X/LTE-V2X. Separating the telematics unit from the NAD yields flexibility and benefits in terms of cybersecurity: an attack on the NAD does not propagate to V2X and the physical isolation helps simplify the certification process.

MediaTek’s automotive-grade cellular modem SoC supports the operating temperature required by the automotive industry, and assures automatic emergency call (eCall) reliable operation even in extreme environmental conditions. It provides data protection, best-in-class connectivity for telematics applications and a highly integrated design for reduced system complexity, lower design costs and a smaller form factor.
