I am about 90 percent done with a design project with a LPC2148 and am looking to the future to integrate ethernet into the project. I was told by a couple of design friends that the LPC series is not a good series for ethernet, because of all the overhead circuitry that the LPC doesn't handle. They are using the STR9 series for their ethernet design, which I was told has better infrastruct...

So it appears the LPC1766 needs an external PHY for the ethernet. Does anyone have an inexpensive chip they would recommend? So far The SMSC LAN8720 is the cheapest I've found, but I would like something even cheaper if I can find it. Another option would be a microcontroller with integrated ethernet PHY. Is there an LPC like that or a chip someone would recommend? I don't need anything...
