Are there any ST ARM core MCUs available with dual ethernet?

[Michael Bauer]

I am searching for an MCU with dual Ethernet. Do any of the ST cores have dual ethernet? Thanks in advance.

Use STM32CubeMX to filter devices by perhiperals and you will find that - no, there are no STM32 devices with more than 1 Ethernet interface.

Thank you. I did that but there was not a count of number of Ethernet ports. I opened every data sheet for those with Ethernet but did not see any that had dual. Thanks for confirming.

Use KSZ8863 or similar (managed) 3-port switch with one MII/RMII and two PHY ports. With proper configuration and software, it can do pretty much everything.

The STM32F107 has an Ethernet port and is about $2. Could you perhaps slave that off your main processor using SPI to provide the second port ? It obviously will run a little slower but may work for some applications.
