Instructions for Using W5100 LQFP80
Power Supply:
- Connect the VCC pin to a stable power supply within the range of 2.6V to 5.5V.
- Connect the GND pin to the ground.
Reset:
- Apply a low signal to the RESET pin to reset the device. The device will also reset automatically on power-on.
Communication Interface:
- Choose between SPI or Parallel interface by setting the appropriate configuration.
- For SPI, connect the SCK, MISO, MOSI, and CS pins to your microcontroller.
- For Parallel, connect the data and control lines as specified in the datasheet.
Configuration:
- Use the provided registers to configure the device. Common configurations include setting the MAC address, IP address, and port numbers.
- Refer to the datasheet for specific register addresses and bit definitions.
Socket Operations:
- Open a socket using the appropriate command.
- Configure the socket type (TCP/UDP) and port number.
- Send and receive data through the socket using the provided commands.
Interrupt Handling:
- Connect the INT pin to an interrupt input on your microcontroller.
- Handle interrupts to manage events such as data reception, connection status changes, etc.
Low-Power Mode:
- Enter low-power mode by setting the appropriate register bits.
- Use the wake-up function to return to active mode when necessary.
ESD Protection:
- Ensure proper handling and grounding to avoid ESD damage.
- Use appropriate ESD protection devices in your circuit design.
For detailed information and specific commands, refer to the W5100 datasheet and application notes.
