The PmodNIC is an interface board for the Microchip® ENC28J60 Stand-Alone Ethernet Controller. The ENC28J60 provides integrated MAC and PHY support, so the PmodNIC can add Ethernet functionality to any Digilent system board.

The primary communications interface with the PmodNIC is an SPI bus. The PmodNIC communicates in SPI mode 0 only, MSB first. An RST pin provides the host with an active low, asynchronous hardware reset for the PmodNIC. The PmodNIC also provides an active low interrupt indicator pin (INT), allowing a host to detect multiple interrupt conditions on the PmodNIC.
