Thank u, Dainis. But the 32bit CPUs seem a bit too much powerful, advenced and complicated for me. I need only the 10/100M Ethernet function. The AX88796 states that it supports MCS-51 series, 80186 series, MC68K series CPU and ISA bus. Meanwhile, the LAN91C111 supports Multiple Embedded Processor Host Interfaces: ARM, SH, Power PC, Coldfire, 680X0, 683XX, MIPS R3000. Do they support solely PIC interface like 16FXX? Does MC68K include MC68HC11? I feel that the new LAN9118 has fulfilled most of the requirement yet it is not that complicated. I'm keen to look into its full detail datasheet but I can only find its "Data Brief". Anyone can suggest me where to get the full datasheet of it, plz??
