Do you know Web51? How about that?
The reason is that I am more familar with 8051.

Hi kathy,
I will try to give You some more examples:
- There are lots of free projects for TCP/IP on PIC-,AVR-Controller and
8051 : i.e. http://www.ethernut.de/ or try "Free TCP/IP AVR" at google
- If You want a controller with more "power" :-) you can have a look at
the ecos site (http://sources.redhat.com) and find a controller
supported by ecos. You can go the same way with other OS as well. So You
can find a controller with appropriate OS-Support and
features/performance You need.
- Use the controller of your choice and XPort (www.lantronix.com) on the
serial port for the network connection.
- There's a book called "TCP/IP lean" from Jeremy Bentham telling You
how to build a small TCP/IP-Stack (with Sources on CD).

Hi,
I just can back from a Renesas (formerly Hitachi/Mitsubushi)
seminar. Basically they were touting that they'll provide reference
code TCP/IP stack for all of their micro products -- for free. This
covers SH-X, H8/300H, H8S/2000, M16C and even H8/300 (in some limited
functionality). The stack runs on RTOS and non-RTOS systems.
The catch is -- you have to buy their micros and sign an NDA
saying that you won't port the code to a different manufacturer ;-)
Ken.

Rabbit Semiconductor has inexpensive, Ethernet-ready microprocessor
core modules and development kits including full development tools and
a robust and mature TCP/IP stack in source code format.

There are no royalties or license fees.

If this is for quick thing, consider the Rabbit Core Modules (
www.rabbitsemiconductor.com ) . They do have TCP Stack along with a
hole lot of other stuff, are fairly cheap etc. To get you started you
must buy one of their SDK's but they are also low priced. Apart from
this there are no royalites or such.
If you have your own hardware design, you may want to port one of
those free TCP/IP stacks to it on your own.

ez80F91 has stack (not stack stack though?) and MAC, so you just need
the PHY to complete. I'm designing "something" with it at the moment,
the devkit is cheap enough, the docs a bit stodgy, and the tools on the
primitive side. But so far so good. You really need the programmer, as
they don't seem to document that side of things much.

I found CMX-MicroNet and some other TCP/IP stack is very expensive for
low volume products. My question are:
1. Is any microcontroller has on-chip TCP/IP stack stack?
2. I heard of eZ80, Maxim's DS400, ... Can anyone tell me how easy to
use it and any hiden cost(have to buy something to use it...)?
3. Is any 8051 with on-chip TCP/IP stack stack available?
