choosing a micro-controller for Ethernet connectivity

Other Parts Discussed in Thread: TIDM-CONNECTED-ETHERNET

Hi,

I want to design a very simple board that turns an LED on/off on the network. I am a good analog designer but I have not designed anything that works on the network so please excuse my ignorance.

I think I need, RJ45 connector => magnet => Ethernet controller => Micro-controller with GPIO.

I want to do it as cheep as possible. Which Micro is the best for my application? Basically, which features are required for a micro to do the job? I mean should they have Ethernet PHY, TCP/IP stack etc? Is there any micro controller that has built in ethernet controller as well?

I was looking for a reference design or application note but I could not find any. can anyone recommend me one please?

Thanks,

-Alex

Hi Alex,

We have a lot of reference designs from TI Designs on Ethernet: http://www.ti.com/general/docs/refdesignsearchresults.tsp?keyword=ethernet

You can consider the AM335x platform.

Along with what Ryan has recommended, you can look at our Tiva C offerings

Since you are asking in MSP430 forum :

I use MSP430+CS8900, there is TI document : SLAA137A

a slimmed TCP/IP Stack is available at TI web site

but it has to be noted that the stack does not provide

DNS/DHCP client related support.

It support raw TCP socket (both client and server, a single connect )

and a very limited HTTP server.
