V2X (vehicle to everything) system provider Unex Technologies and STMicroelectronics have teamed up to collaborate on V2X communications platforms for developers. 


Unex has integrated its V2X system-on-a-module chipset and its V2Xcast software stack with STMicroelectronics’ modular telematics developer platform to form a customizable solution for V2V and V2I (vehicle to infrastructure) applications prototyping.


“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 of infotainment at the automotive digital division at STMicroelectronics, in a statement. “This joint effort aims to accelerate the adoption of next-generation systems for autonomous and safer connected cars.”


STMicroelectronic’s Telemaco3P modular telematics platform is the company’s development platform for its Telemaco3P system-on-a-chip. It provides an open development environment for prototyping advanced smart driving applications. It uses a secure automotive processor, positioning hardware and “dead-reckoning” sensors. The company claims its automotive processor is the industry’s first device to have an embedded and isolated hardware security module (HSM), which is able to check the authenticity of external devices trying to connect to the car.


It also uses STMicroelectronics’ automotive-grade multi-constellation GNSS Teseo IC, which the company claims is the world’s first multi-band GNSS receiver with autonomous-driving precision and automotive safety compliance. It uses multi-constellation tracking to correct the vehicle’s positioning error in order to deliver “high-precision” navigation.


The telematics platform supports connectivity to automotive buses such as CAN-FD, FlexRay, and BroadR-Reach, and offers modules for Bluetooth, Wi-Fi, and LTE.


Unex’s SOM-301 is a self-contained system-on-module that integrates V2X hardware and software components, with both dedicated short-range communications (DSRC) and C-V2X connectivity supporting LTE and 5G. The system-on-module includes Autotalks’ Craton 2 processor, which meets V2X security standards.


Unex’s chipset and software stack will handle secure V2X communication on one side, while STMicroelectronics’ Telemaco3P will manage the applications. Unex EVP Nick Lee said the integrated offering will provide a “time-to-market accelerator for developers.”
