To connect the PmodNIC100 Ethernet Controller Module to your system board, you will need to follow these steps:
1. Identify the 12-pin Pmod connector on your system board.
2. Align the PmodNIC100 module with the Pmod connector, ensuring that the pins match correctly.
3. Gently press the module onto the connector, making sure it is securely attached.
4. Connect the other end of the PmodNIC100 module to your system board's power supply and ground pins. The VCC pin should be connected to a 3.3V power supply, and the GND pins should be connected to the power supply ground.
5. Connect the CS, MOSI, MISO, and SCLK pins of the PmodNIC100 module to the corresponding SPI pins on your system board.
6. Leave the ~INT/SPISEL pin floating or at a logic level high voltage within the first 1 to 10 μS to enable the SPI mode.
7. Bring the Chip Select (CS) line to a logic low voltage state to initiate communication with the Ethernet Controller.
Please refer to the Pinout Description Table in the user manual for the specific pin numbers and signal names.
Note that the PmodNIC100 module only provides the hardware at the physical layer (PHY) and the media access control (MAC) for a network interface. You will need to provide your own protocol stack software, such as TCP/IP, to enable network communication. Digilent provides a set of libraries for Ethernet support, which can be downloaded from the PmodNIC100 product page.
Make sure to adhere to the recommended power supply voltage range of 3V to 3.6V for the PmodNIC100 module. Operating it at 3.3V is strongly recommended.
