We are currently developing multiport product, we would like to consider using W3150A, however, the high pin count of MII is really a big problem. Is there a plan for you to add an option to W3150A so that a RMII interface could be selected by user, for example, with a ‘mode’ selecting pin (between MII and RMII)?
All WIZnet TCP/IP chips do not support RMII.
We are considering to support RMII in the future. But, Currently not yet.
