STMICROELECTRONICS AEK-COM-10BASET Evaluation Board, SPSB0813-TR, 10BASE-T1S Ethernet Controller

AEK-COM-10BASET is a 10BASE-T1S MAC-PHY evaluation board. This is a powerful tool to explore various vehicle network architectures, leveraging on new 10BASE-T1S automotive Ethernet protocol implementation and other on-board legacy automotive interfaces (CAN, CAN-FD and SPI). This board merges the innovations brought by the new 10BASE-T1S specification with high-performance dual-core SPC58EC80E5 chorus family MCU. It meets requirements of new megatrends in automotive industry, such as personalization, electrification, autonomy, full connectivity, which are moving in-vehicle networks away from domain-based solutions, gravitating towards new zonal architectures. The 10BASE-T1S automotive Ethernet enhances IVN architectures by connecting sensors, car body and infotainment ECUs. This protocol supports half/full-duplex communication, allowing either point-to-point direct connection between two nodes, or use of multidrop topology with up-to-eight nodes connected on a single 25m bus segment.
