I have been using PIC32 microcontrollers but am looking at switching to the STMicro line of microcontrollers. One thing that Microchip has that is really nice for industrial products is an external PHY chip with a built in 3 port 10/100 switch. This allows 1 port to connect to the microcontroller and have 2 ports to connect to magnetic jacks, allowing you to daisychain devices. This can be seen here:
I just wanted to know if anyone knows of anything similar that can be done with the STMicro products out of the box. A driver should be possible to use the Microchip PHY with the STMicro parts, but I have not seen any direct drivers for them.
This is a key feature for me when developing industrial devices, so I want to make sure I can make this work before switching platforms. Everything else I do on Microchip devices looks like it can be done easily enough, so this would be the main hurdle for me.
