Merhaba Yahya Bey,
Interestingly I've also tried MCF52235 along with AX11025. MCF52235 is a 32 bit mcu and ax11025 is an 8051 compatible 8 bit one. It is difficult to compare the two both in performance and price. Nevertheless ax11025 is well suited for my project and has useful capabilities.
Although you can find much more detailed datasheets, application notes and user posts about Freescale mcu's, the documents Asix supplied are quite enough. Besides they have support engineers replied all the e-mails I've sent. I'm using Keil complier and it's not free.
Freescale stack has a simple opertaing system and the other doesn't have that. But I'm fine without an OS. For both mcu's the stack is soft. Asix hardware can process arp packets but that is optional and you can still use and edit software stack in all layers.
Regards,
Selcuk
