Ethernet Modes Supported for STM32H757XI

[JananiRamesh]

As given on datasheet this microcontroller can support 10/100 Base T Ethernet. Is there any probability that this microcontroller supports Gigabit Ethernet and if yes, please provide the recommended circuitry for the same.

[LCE]

Not possible.

H7 ETH MAC supports 100M max.

Check the STM32MPx series, (some of) these have Gigabit MACs.

Edit: maybe there's a solution with an extra IC, something like "SPI-to-Gigabit".
