Infineon Technologies AG has launched the TRAVEO CYT4EN, a new automotive microcontroller designed for affordable, high-performance instrument clusters and display systems, including applications in two-wheelers.
The MCU uses external LPDDR4 memory to deliver advanced capabilities typically associated with more complex system-on-chip platforms. It supports 2.5D graphics and 3D scene rendering, enables Full HD displays, and can operate two displays at the same time. By combining these features in a cost-efficient MCU architecture, the TRAVEO CYT4EN can help reduce system complexity and overall bill-of-materials costs compared with SoC-based solutions.
“Cutting-edge cluster and display solutions are playing a central role for the user experience in connected and software-defined vehicles,” said Thomas Boehm, Senior Vice President Automotive Microcontrollers at Infineon. “With TRAVEO T2G CYT4EN, we are helping our customers bring them to market more quickly, efficiently and cost-effectively. By combining the simplicity, safety, and fast responsiveness of an MCU architecture with the high-bandwidth memory required for modern cockpit graphics, we are enabling a new generation of vehicle displays.”
While developing CYT4EN, Infineon collaborated closely with Micron to optimize the memory subsystem for the use of LPDDR4 memory to support advanced graphic capabilities while maintaining overall system efficiency.
“Micron’s automotive LPDDR4 memory provides a proven combination of bandwidth, reliability, and functional safety features for cost-optimized cockpit platforms,” said Amanda Henderson, Director of Ecosystem Enablement at Micron. “For vehicle programs where affordability, longevity, and functional safety are key requirements, LPDDR4 remains an effective solution for delivering modern display experiences.”
Built on the proven TRAVEO T2G architecture, the CYT4EN combines high-performance processing, advanced graphics, and automotive-grade safety and security in a highly integrated device. It includes features such as on-the-fly rendering and hardware-accelerated decompression to enable a rich graphical user experience. The device delivers deterministic boot times below 150 milliseconds that are significantly shorter than the multi-second initialization common to complex SoC platforms. It supports functional safety up to ASIL-B according to ISO 26262 and was developed in accordance with ISO 21434 for automotive cybersecurity. In addition, an independent voltage domain keeps central system functions such as communication and basic processing active in low-power modes, improving system efficiency and robustness.
The high level of integration enables cost-effective smart cockpit designs without complex system implementations. For example, CYT4EN allows designs without additional microcontrollers for system management and in-vehicle network communication, enables simplified PCB layouts with as few as six layers, and avoids the need for active cooling thanks to optimized power efficiency.
