Unex and STMicroelectronics collaborate on V2X and secure telematics

Unex Technology, a provider of V2X (vehicle-to-everything) systems, and STMicroelectronics, a semiconductor company serving customers across the spectrum of electronics applications, have announced the integration of Unex’s SOM-301 V2X system-on-module on STMicroelectronics’ Telemaco3P Modular Telematics Platform (TC3P-MTP).

Unex’s SOM-301 is a self-contained system-on-module that integrates all V2X essential hardware and software components and features Unex’s V2Xcast technology. SOM-301 devices integrate ST’s Teseo III automotive multiconstellation GNSS chip and Autotalks’ CRATON2/PLUTON2 secure V2X chipset, capable of both DSRC and C-V2X (PC5) connectivity.

The Telemaco3P Modular Telematics Platform provides an open development environment for prototyping smart driving applications. At its core is ST’s Telemaco3P secure automotive processor, said to be the industry’s first device with an embedded isolated hardware security module for high security. The platform provides positioning hardware with ST’s automotive-grade multiconstellation GNSS Teseo IC and dead-reckoning sensors. It also offers direct connectivity to automotive buses such as CAN-FD, FlexRay and BroadR-Reach (100Base-T1), as well as optional modules for Bluetooth, Wi-Fi and LTE.

Unex’s V2Xcast software stack enables extended capabilities for the V2X processing; the CRATON2 on SOM-301 handles secure V2X communication on one side while the Telemaco3P manages the applications, fusing the V2X messages with data from in-vehicle, Wi-Fi or cellular networks.

The integration of Unex’s production-ready SOM-301 onto ST’s Telemaco3P Modular Telematics Platform results in a solution that can easily be customised at both hardware and software levels, enabling near-final V2V and V2I applications prototyping and shortening time to market.

“Integrating our V2X technology within the comprehensive STMicroelectronics Telemaco3P ecosystem was extremely important for us,” said Nick Lee, Executive VP of Unex Technology. “After a quick and straightforward integration with the module and the platform, we are excited to have our SOM-301 on ST’s Telemaco3P MTP. The integrated offering provides [a] time-to-market accelerator for developers.”

“The objective of our collaboration with Unex is to provide our partners and customers with an easier and faster path to V2X solutions,” said Antonio Radaelli, Director Infotainment, Automotive Digital Division, STMicroelectronics. “Together with our automotive GNSS solutions, this joint effort aims to accelerate the adoption of next-generation systems for autonomous and safer connected cars.”
