Overview
The Digilent PmodNIC100 is a standalone Ethernet Controller to provide Ethernet functionality to any system
board.
1 Functional Description
The PmodNIC100 utilizes Microchip's ENC424J600 Stand-Alone 10/100 Ethernet Controller. By providing both MAC
and PHY support, Ethernet functionality at data rates up to 10 Mbit/s is achievable for any system board.
2 Interfacing with the Pmod
The PmodNIC100 communicates with the host board via the SPI protocol. By leaving the Interrupt/SPI Select
(INT/SPISEL) pin floating or at a logic level high voltage within the first 1 to 10 μS, the SPI mode is enabled. Users
may then bring the Chip Select (CS) line to a logic low voltage state to initiate communication with the Ethernet
Controller.
Note that this Pmod only provides the hardware at the physical layer (PHY) and the media access control (MAC) for
a network interface. Users must provide their own protocol stack software (such as TCP/IP). Digilent provides a set
of libraries providing Ethernet support that is available for download on the PmodNIC100 product page.

Any external power applied to the PmodNIC100 must be within 3V and 3.6V; however, it is strongly recommended
that the Pmod is operated at 3.3V.
3 Physical Dimensions
The pins on the pin header are spaced 100 mil apart. The PCB is 1.8 inches long on the sides parallel to the pins on
the pin header (2.05 inches long including the Ethernet port) and 0.8 inches long on the sides perpendicular to the
pin header.
