Instructions for Use

1. Power Supply:

   • Ensure that the supply voltage is within the specified range of 3.3V 卤 5%.
   • Use a stable power source to avoid voltage fluctuations.

2. Temperature Considerations:

   • Operate the device within the temperature range of -40掳C to +85掳C to ensure reliable performance.
   • Avoid exposing the device to extreme temperatures or rapid temperature changes.

3. Pin Connections:

   • Refer to the pinout diagram in the datasheet for correct pin connections.
   • Ensure proper grounding and decoupling capacitors are used as recommended in the datasheet.

4. Configuration:

   • The on-chip EEPROM can be used to store configuration settings. Use the provided software tools to program the EEPROM.
   • Verify the MAC address assignment and configure any necessary network parameters.

5. MDI/MDIX:

   • The device supports auto MDI/MDIX, which automatically configures the connection type. No manual crossover cables are required.

6. Flow Control:

   • Enable flow control using the IEEE 802.3x standard to manage data traffic and prevent buffer overflow.

7. 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.

8. Jumbo Frames:

   • Enable jumbo frame support if your network infrastructure supports frames up to 9000 bytes.

9. ESD Handling:

   • Handle the device with care to avoid ESD damage. Use grounded wrist straps and anti-static mats during handling.

10. Testing:

    • After assembly, perform functional tests to ensure all features are working correctly.
    • Use network diagnostic tools to verify connectivity and performance.

For detailed information and additional specifications, refer to the official datasheet and application notes provided by the manufacturer.
