SPE looks really interesting for CAN/RS485 replacement.

I just noticed Analog devices also has chips finally available even at resellers: ADIN1100 for pure phy like the TI part in this but more interesting once are ADIN1110 (spi bus to MAC+PHY so any mcu with spi bus can communicate with ethernet) and especially ADIN2111 which is 2xSPE PHY + MAC + spi bus so with single chip you can make daisy-chain devices talking at 10base-t1l and the ADIN2111 has simplified rx/tx interface so with small transformer nice galvanically seperated link can be made.

Until now I have used isolated CAN transceivers for links between devices that need ~100m distance as quite many MCU have built-in CAN peripherals but ethernet MAC is usually restricted to the bigger series. The spi bus on the ADIN (and probably later some other chips similar to the ENCJ from microchip) opens this up to smaller lower end devices.

I am really excited for the coming years as I have been waiting for these 10base-T1L devices to be available for roughly two years and the chip shortage in general has not made things easier.
