Hardware recommendation for Ethernet application

[JColvin]

A customer on our website asked the following question:

I have a project needing a controller with Ethernet and 25 GPIO, 20 data/address and 5 handshaking. The controller will be sent a small UDP packet with two 16 bit values which it will then write into a PIO interface on another device. The controller will then read two 16 bit values from the PIO device and send a return UDP. Suggested hardware?

The response is below.

Hello,

I have asked some of our applications engineers about this to see what they would recommend; they'll get back to you here on the Forum.

Thanks,

Hello,

I would suggest the chipKit pro Mx4 or the chipKIT pro Mx7.  Both have an Ethernet , 25 GPIO and 20 data/address. I'm not sure what you mean by 5 handshakes, but they both have 5 external interrupts. 

thank you,

Jon
