We are looking for a Serial TTL to Ethernet ready solution.
Firstly we bought an WIZ107SR module and it worked properly. Then, to minimize costs, we decided to use the IOP W7100A (8051, TCP/IP, MAC & PHY) in our project.
But also, there is the IOP W7500P, which is composed by an Cortex-M0, TCP/IP, MAC & PHY.
It seems this second item meets our need too and it is cheaper. Could you confirm it?
We appreciate your attention.
