hello all,
i want to interface Ethernet Controller IC with MCU.
i have searched and got the two most commonly used ICs ENC28J60 and RTL8019AS.
i am working with ATMEL 89SXX MCU.
can any one tell me which MCU I should use for this interfacing. why?
can I do it using 89SXX MCU.?
and after successful interfcaing, want to send the data to PC via LAN.
can it be Possible..??
can any one help me.??
Thanking you all in Advance...

For ENC28J60 you can use any microcontroller that has SPI interface, because ENC28J60 connects through SPI.
The memory requirements vary, depending on the application. For an embedded web server that displays some html pages you may need an external memory on SPI or I2C.
It will work - you should write the program in C - it's a difficult work if you need to implement many protocols. You can find examples with ENC28J60, many of them for AVR microcontrollers, but the souce being in C maybe you can adapt it for you microcontroller.

| For a small microcontroller Wiznet W5100 may be more appropriate. ww.wiznet.co.kr It's a controller with a hardware IP stack, thus considerably reducing the software overhead in uC.

Thank you for replaying...
i would like to prefer ATMEL first if its working because i have much Experience of ATMEL and it will be available easily also near by our town.
we know that coding will be more but before that
can you please give me some more details regarding this communication.
i mean how to interface the Ethenet Controller IC with MCU and which one will be best for easier communication with less possible coding.
and tell me one thing what is the meaning of "TCP/IP Stack"..??
where and how it can be utilize..??

| TCP/IP stack means the code handling the TCP/IP protocol, anything that is necessary between a send() or receive() function call in your application code and the ethernet controller hardware, may be a few hundred up to thousands lines of code.

Thanks Eugen_E,
let me get details of AVR and its availibility near by our Town.
i'll be back if i'll found difficulty.
Thnka you all

no.. 
sorry i have no exp. about PIC.
i have used ATMEL only till today.

You can use a PIC16F84 but you will have some trouble. There's two things that are a problem. The first is that it only has 13 IO pins so you can not use the parallel interface with the W5100. The second is that the 16F84 doesn't have SPI either.
There is a way around this though but it requires a bit of software. The way you can do it is write your own SPI port (basicaly bit bang the data out). This might get a bit complicated though because you have to cample the data at specific times in the clock cycle though its simple enugh to implement if you have experience with PICs.

This link below is not working.
The implementation of TCP is simplified to transmit only 1 TCP segment. You can find complete UDP, TCP, HTTP implementations
