ETH: anybody used KSZ8863RLL?

LCE

Heyho,

until now I only used STM32 with the LAN8742, in a few weeks I'll get my 2nd custom board, but this time with the "dual" PHY KSZ8863RLL.

It's connected via RMII, for setup MDIO (and optionally I2C for the registers not accessible via MDIO).

Are there any known issues or "pitfalls" with this PHY?

Thanks in advance,
LCE

PS: interesting that there is no "ETH" label... :D

You mean this: https://www.microchip.com/en-us/product/lan8742 ?

and this: https://www.microchip.com/en-us/product/ksz8863 ?

As they're both Microchip products, have you asked Microchip for any guidance in moving from one to the other?

Do they have a migration guide?

Or on the Microchip Ethernet forum:

I guess that would go under 'Interface and connectivity ICs':

But do ST have any such chips?

No PHYs from ST.

That's why I ask here, in hope some other STM32 user has used the KSZ8863.

The Microchip forum / Ethernet feels like mostly dead.

They have a migration guide between the KSZ8863 and another dual PHY.

Yes, I already found these, one thread was started by me...

And I'm not too bad at googling! 😉

I'd rather have some insights from another STM32 / PHY user.

The products are agnostic to what microcontroller is used - a SAM would see the same as an STM.

Microchip would be able to tell you about the differences between their products.
