Frequently asked questions
Can I use it on a breadboard?
No. It comes in a QFN32 package, so it requires a PCB design and the external components specified in the datasheet.
What else does an Ethernet design need?
Ethernet controllers generally require magnetics for the RJ45 interface, a clock source and power decoupling, as detailed in the datasheet.
