Lpc2000

From what I recall the DP83847 and DP83848 are PHY only.  They produce a MAC interface, not a MCU interface.  If you had an ARM-9 like a 946 or something with a MAC built in, they would be a good choice.  But for use with an ARM-7 like LPC2000, using something like the SMSC parts with PHY+MAC I think is a lot easier.

  Another alternative would be the latest 10/100 PHY from National 
  which has been designed to operate with embedded microcontrollers. 
  More info at http://www.national.com/pf/DP/DP83848C.html. They also 
  offer a 10/100 MAC+PHY (http://www.national.com/appinfo/networks/) 
  plus a rather useful "Ethernet Made Easy" on-line design tool which 
  I've found useful.

  parts, with lots of other source code around and RTOS support for 
  stacks.  For the USB-2 I picked the Philips ISP1582.
