STM32 setup with 2 x HS controllers

[donpedro]

Hello all,

Is there a way to setup a system with 2 x USB High Speed controller easily on an STM32 controller?

As far as I can tell, even the STM32H7 only has 1 HS PHY (ULPI interface), as the other one is FS only, even though the internal controller is HS.

1) Is this limitation true, or does there exist any STM32 with 2xUSB HS ?

2) Is there a way to easily add a secondary HS controller to an STM32?

Any interface will do (SPI or similar for data):

Thanks,

/pedro

Hello @donpedro​,

I recommend you to use the STM32MPU1.

This device have two physical ports supported using an on-chip 2-port high-speed PHY.
