Infineon Technologies KITA2GTC39724VGTW 24V Automotive Gateway Board

Infineon KITA2GTC39724VGTW 24V Automotive Gateway Evaluation Board can cover various automotive and CAV applications. Either for a gateway, sensor fusion, or telematics systems, this evaluation board is the ideal solution for bringing projects out of the paper. This evaluation board brings the right environment for rapid prototyping while minimizing R&D efforts and time to market. The Infineon KITA2GTC39724VGTW 24V Automotive Gateway Evaluation Board features two powerful AURIX™ TC397 microcontrollers combined with Realtek's RTL9047AA automotive Ethernet switch. The two AURIX TC397 MCUs bring the well-known multicore computing performance, flexibility, scalability, integrated safety, and security support of the AURIX 2nd generation family. The MCUs support communications interfaces featuring a Gigabit Ethernet interface, multiple ISO 11898-1-compliant CAN FD channels, and LIN and FlexRay channels. An additional eMMC interface for external flash interfacing enables local data storage, supporting software-over-the-air update concepts.

Realtek’s RTL9047AA automotive Ethernet switch controller features five integrated 100Base-T1 PHY transceivers, one fast Ethernet PHY, and up to two full-featured xMII interfaces. This provides access via an external CPU or a cascade switch. The RTL9047AA switch is AEC grade 1 qualified. The 24V Automotive Gateway board is prepared to address the most challenging E/E architectures. The AURIX TC397 is connected with a 1Gbps RGMII port to the Ethernet Switch for data transfer and an SPI channel for managing the Switch. The RTL9047AA provides five 100Base-T1 Ports together with the RosenbergerH-MTD® connector set to provide the right feature set to connect the Automotive Gateway Board to an In-Vehicle Network. In total, 16 CAN-FD connections, 4 LIN, and 4 FlexRay channels, half on each CPU, allow bridging of different network topologies. CPU A offers a PSI5-S connection with four channels. CPU B provides a Raspberry Pi-like extension header to add extension Boards like pHAT. Both CPUs are connected with two high-speed HSSL channels and one SPI channel.
