Ethernet controller interface with microcontroller - Page 3 - Electronic Circuits Projects Diagrams Free

Regarding the DS80C400 - I have had nothing but problems putting it into a project. By all means find something else, either a micro with CS8900A or ENC28J60, or a micro with embedded ethernet like the PIC one. But don't use the DS80C400!

Just because you can put together an 8051 system with external memory and an SPI Ethernet controller still doesn't make it a good idea. You still have no DMA into RAM with the 8051 architecture which means no full duplex operation, so your going to have a difficult time keeping up. This thread is nearly a year old, so if this is such a good idea, how come nobody has done it?
