Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range of 3.3V ± 5%.
   • Connect the power supply to the Vcc pin and ground to the GND pin.

2. Host Interface Connection:

   • Connect the host interface (PCI, PCI-X, PCI Express) to the appropriate pins on the device.
   • Ensure the data bus width (16-bit or 32-bit) is configured correctly.

3. PHY Configuration:

   • The integrated PHY supports MII, RMII, and RGMII interfaces. Connect the MDI (Medium Dependent Interface) to the network medium (e.g., twisted pair cable).

4. MAC Address:

   • The device has a built-in MAC address. If a custom MAC address is required, it can be programmed via the host interface.

5. Flow Control:

   • Enable flow control using the IEEE 802.3x protocol to manage data transmission rates and prevent buffer overflow.

6. Wake-on-LAN:

   • Configure the wake-on-LAN feature to allow the device to wake up from a low-power state when a specific network packet is received.

7. LED Configuration:

   • Connect the LED pins to external LEDs to indicate link status, activity, duplex mode, and speed (10/100 Mbps).

8. ESD Protection:

   • Handle the device with care to avoid electrostatic discharge. Use proper ESD protection measures during handling and installation.

9. RoHS Compliance:

   • The device is RoHS compliant, ensuring it meets environmental standards for hazardous substances.

10. Operating Temperature:

    • Operate the device within the industrial temperature range of -40°C to +85°C to ensure reliable performance.

11. Power Consumption:

    • Monitor the power consumption, which is typically 250 mW in active mode, to ensure it does not exceed the power budget of your system.

12. Testing and Validation:

    • After installation, perform testing to validate the functionality and performance of the LAN91C111I-NU in your application.
