Lpc2000

I sent them an email (actually, I think it was through their support
web page) after someone here said they got samples that way.  I
received a reply saying they would send me samples.  This was the 2124
which is not currently available, so I guess ES are available on most
of these parts.  

Go to the web site and go through the contact or support page.  

BTW, I also requested samples when someone posted the web page.  But
the sample link turned out to be for the LPC900 parts and that is what
I received.
