AM2431: Alternative Recommendation

You can check the TM4C1294NCPDT series. https://www.ti.com/product/TM4C1294NCPDT?bm-verify=AAQAAAAJ_____xr0RMoyy6MQAE21n7zQ7u8zafyrmYZVk1tJCY8MU1uI1HM40jVyMPGaGzhJAjg8-vuCp58zhJLFB0IlBICLTmOE04IXugo8sn8JXPU0xD0sz4uGOJH-3xQCe8CopfrjYy25KPQE6_tNXUaLwbEBPaK7cES0CMSQRspSRbIB8qQ1787mUF0aqw5sqz-Jf5QpYhTtGapNDV3z0FUPeDMwb1k7MreQ7rnNqC2nJEz1Lh6sbSjjqfzgrPB_o2gNCnC8tJfXxGI8FWXi-L9_XX3nMsZO3gn1C15RT96ev1CQ1l5dK0i3KJw4vfwM  This MCU features an integrated Ethernet MAC with an RGMII interface, and it also supports SPI. You can also check the Sitara AM335x  Series. This Sitara processor includes an RGMII interface for Ethernet connectivity and multiple SPI interfaces. For a TI Ethernet switch solution similar to the KSZ9897 from Microchip, you might consider DP83869HM or DP83867IR. Hope you'll find your alternative solution from these. In the meantime you can take a look at this board with   2x WLAN, Ethernet and 4 USB ports.  www.pcbway.com/.../ArdOSD3358.html
