cheapest way for embedded TCP/IP stack?

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?

  1. 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...)?

  2. Is any 8051 with on-chip TCP/IP stack stack available?

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.

If this is for quick thing, consider the Rabbit Core Modules (

) . 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.

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.

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 ;-)

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.

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

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

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).

There are several free TCP/IP stacks that are appropriate for microcontrollers.

All of the above have been ported to numerous MCUs as well as several open source and commericial RTOSs.

Do you know Web51? How about that?

The reason is that I am more familar with 8051.
