W7100A or W7500P?

Dear support,

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.

Best Regards
André W.


I think… you must using W7100A IOP.

Because, W7500P is remain bug.

So, W7100A recommendation for you.

thank you
