hey all, I've worked a bit with ethernet in the past, using things like ethernut. I am looking looking forward to starting some more advanced ethernet projects. I don't have as much of an understanding as I would like of low-level ethernet (i.e. MAC, MII, PHY, ,magnetics, frames, layers, etc). If anyone can reccomend some websites/books/etc where I can gain a better understanding of the...

Does anyone know when (or if) the LPC3000 range will be extended to include a processor with Ethernet support? I have an application where the LPC3180 would be ideal if it had built-in ethernet. It's a very cost-sensitive project so I can't justify an off-chip ethernet option. I may have to resort to another manufacturer (much to my annoyance). Any clues??? Regards, David
