'[PIC]: RTL8019 Realtek Ethernet chip'

Has anyone had any success using the realtek RTL8019 Ethernet chip?

Is this the easiest chip to interface an 16F877 to?

That's what Fred Eady's Packet Whacker is all about. He first wrote
about it in Circuit Cellar:

  PDF: http://www.circuitcellar.com/echips-pdfs/1001/c1001fepdf.pdf

You can find the followup to this and more of Fred's articles, which
often deal with PICs and/or Ethernet, by consulting my index:

Maybe, or maybe the CS8900 is.

I'm just curious if anyone here has had any experience with using RTL8019 chip?
If I purchase this chip and mount it on my own pcb will the RTL8019 require any programming like a PIC, or is it a pre-programmed chip that I can interface directly to a PIC with minimum effort?

I don't know anything about this chip, didn't you find such basic answers
when reading the data sheet?  That's the first thing I would do if I had
such questions.

The electrical interface between the two is simple, the 8019 is not very
complex, but if you want to implement TCP/IP, there is a lot of software
that has to run on the PIC etc.

The RTL8019 is a well known ethernet chip that is a NE2000 clone. It has
no memory on chip and uses programmed IO for communication afair. This
requires a zippy cpu and lots of programming to make it work.

The often-used RTL8019AS has 16K bytes of SRAM built-in.
