W5500 Ethernet Network Module

• Hardware TCP/IP Interface: Support for TCP, UDP, ICMP, IGMP, IPv4, ARP, IGMP, PPPoE, and Ethernet protocols.
• Ports: Support for 8 independent sockets.
• Packaging: Very compact LQFP48 lead-free.
• Sleep Mode: Provides sleep mode and network wake-up.
• SPI Connection: Support for SPI speed (SPI mode 0, 3).
• Memory: Internal 32K byte memory as TX/RX cache.
• Ethernet Physical Layer: Support for 10/100Mbps.
• Auto-negotiation: Support (10/100-Based full/half duplex).
• Operating Voltage: Operating voltage 3.3V, the I/O ports withstand voltage of 5V.
• Signal Indications: Multiple signal indication outputs.

• Function Description Table:
  • 3.3V: 3.3V power input
  • 5V: 5V power input
  • MISO: SPI master input slave output
  • GND: Power ground
  • MOSI: SPI master output slave input
  • RST: W5500 reset pin (active low)
  • SCS: SPI SLAVE select pin (active low)
  • INT: W5500 interrupt pin (active low)
  • SCLK: SPI clock pin

Note: The operating voltage of the W5500 is 3.3V, but the I/O port can withstand 5V. The YIXIN_W5500 module has two power supply modes, 3.3V or 5V. When using 5V power supply, the output of the "3.3V" pin is 3.3V.
