Infineon, MediaTek Enable Cost-Efficient Infotainment Solutions

The trend in the automotive industry is towards digital cockpits, with buttons and controls disappearing from the dashboard and being replaced by advanced displays. As one of the key systems in a vehicle, the digital cockpit system needs to deliver high performance features to the vehicle users while meeting functional safety targets.

The traditional way to achieve such goals is to run the digital cockpit system on a high-performance SoC with a hypervisor. However, the up-front investment required to get started with such a system is in the seven-figure range, and the license fees for the operating system and hypervisor add to the overall cost of the system, making it economically unattractive for mid- to low-end car models.

Infineon Technologies AG, together with MediaTek and its design house partners, has developed an easy-to-use cockpit solution based on Infineon’s TRAVEO CYT4DN MCU family and an entry-level MediaTek Dimensity Auto SoC solution that reduces system BOM costs for both hardware and software.

In this easy-to-use cockpit solution, the Infineon CYT4DN MCU works as a safety companion to the SoC to meet the ASIL-B safety target for automotive clusters. The TRAVEO MCU monitors the content rendered by the SoC and takes over with reduced functionality in case of an error, in addition to normal companion functions such as communication with the vehicle network.

“Our automotive SoC, combined with Infineon’s TRAVEO T2G MCU, will provide a cost-effective cockpit solution that delivers new possibilities to OEMs and Tier 1 companies,” said Xiong Jian, vice general manager of the Automotive product line at MediaTek. “This option will greatly boost the performance and capabilities of the cockpit in entry-level car models.” 

“A modern cockpit supports the driver and increases driving comfort for all vehicle occupants. That is why it is important to us that cost optimized vehicle models can also be equipped with digital solutions. Together with MediaTek and our partners, we are pleased to pave the way for digital cockpits for all vehicles,” said Ralf Koedel, VP microcontroller smart mobility at Infineon. “The TRAVEO T2G CYT4DN MCU incorporates our low-power flash memory, multiple high-performance analog and digital peripherals and enables the creation of a secure computing platform.”

This new cockpit solution supports a resolution of 1920 x 720 pixels for clusters and the in-vehicle infotainment display. The cluster display is driven by the ASIL-B-compliant TRAVEO CYT4DN MCU, ensuring high reliability.
