But maybe it's better to use a CPU with integrated ethernet. It's cheaper, you'll get much more CPU power and there are less risks.
Good idea, look:
Samsung ARM core System on Chip (SoC) S3C4530A 16/32-bit RISC microcontroller
is a cost-effective, high-performance microcontroller solution for Ethernet-based systems. An integrated Ethernet controller, the S3C4530A, is designed for use in managed communication hubs and routers.
Important peripheral functions include two HDLC channels with buffer descriptor, two UART channels with full modem interface signal and 32byte buffer, 2-channel GDMA, two 32-bit timers, and 26 programmable I/O ports. On-board logic includes an interrupt controller, DRAM/ SDRAM controller, and a controller for ROM/SRAM and flash memory.
It price is about 15 $ USD, add SDRAm and FLASH and Ethernet PHY.
