Today’s embedded systems are small, fast, and very
powerful. Embedded connectivity stands at the forefront of harnessing the power of these systems. The CP220x is an Ethernet controller that integrates Ethernet functionality into a single 5×5 mm package. When placed in an embedded system with a microcontroller, it provides embedded Ethernet connectivity.


This design guide discusses the benefits of embedded Ethernet and presents three easy steps for adding Ethernet connectivity to your embedded system: system definition, hardware design, and software development. It also provides time-saving tips and suggestions to simplify implementation.
