Hello:

I have an Ethernet Switch with a MII MAC interface on my main board. There is a connector on the main board that allows for an optional daughter card. The interface on the connector include the MII MAC interface as well as a UART & SMI. On the daughter card I had planned to use an Atmel AVR32 AT32UC3A; however that also has an MII MAC interface. Any idea how to get around this? The main board is already completed so it can't be changed. The daughter board is flexible because its being designed.

For the uC I'm particularly interested in:
UART, USB OTG, Ethernet Controller
Internal 256/512 KB Flash, 64 KB SRAM
100-LQFP
i-temp

Thanks.
Gavin
