Overview

The PmodNIC100 is a peripheral module

designed to provide a complete Ethernet

interface. It features the Microchip®

ENC424J600 Stand-Alone Ethernet Controller.

The ENC424J600 provides integrated MAC

and PHY support, so the PmodNIC100 can

add Ethernet functionality to any Digilent

system board.

Features include:

• standard SPI interface

• 10/100 Mb/s data rates

• IEEE 802.3 compatible Ethernet

controller

• MAC support

• 10BASE-T support

• 100Base-TX support

Functional Description

The communications interface between the

PmodNIC100 and the host system board uses

an SPI bus. The PmodNIC100 communicates

in SPI mode 0 only, MSB first.

The INT/SPISEL pin is used by the

ENC424J600 to select use of the SPI interface

or a parallel interface. The INT/SPISEL pin

must be high when the ENC424J600 leaves

the power on reset state to enable the SPI

interface. This happens within 1µs to 10µs of

power on. Once completed, the INT/SPISEL

pin functions as an active low interrupt signal,

allowing a host to detect multiple interrupt

conditions on the PmodNIC100.

For more information about the hardware

connections, see the PmodNIC100 schematic

at www.digilentinc.com.

The PmodNIC100 provides only the hardware

for a network interface. Protocol stack software

(such as TCP/IP) must be provided by the

user. The Microchip Applications Library,

available from the Microchip web site, provides

full network stack support for the ENC424J600

Ethernet controller.

For more information about the ENC424J600

Ethernet Controller, see the data sheet at
