It depends on what he wants to use it for.
Personally, I use Microchip's ENC 28J60 10 Mb/s mac+phy for SPI, it
allows me to receive/send ethernet frames. No TCP. They have an improved
version for 10/100 Mb/s network with a parallel port access (+ spi).
For one project I designed-in an SMSC's 10/100 MAC+PHY in one chip, that
had 16/32 bit parallel SRAM like interface.
If the cost is the question, then for FPGA designs, an PHY-chip is
enough, with MAC implemented in fpga.. that can be the way to get to
1000 Mb/s.
For the TCP/IP stack I do not know any chips - just an assembly called
XPORT. Some versions have eth-serial only, some offer TCP stack. I
haven't worked with them.. I have my own stack now :)
I suppose they will use some AT command set like interface, to
initiate/receive TCPIP.
those have an arm7tdmi embedded
others have some sort of embedded x86 proc
Are they reprogrammable then? It then resembles the Rabbit modules, they
had some processor with Ethernet too.
