W5500 ethernet network module integration hardware TCP/IP protocol; Internal 32K byte memory as TX/RX cache; Support 10/100Mbps transmission rate; Support 8 independent ports to run at the same time ^^ Support 3.3V or 5V power supply, 5V power supply can also output 3.3V power supply, convenient for users to use in different single chip microcomputer systems; The communication mode between the module and the single chip system is simple and convenient SPI communication. ^^ Supports hardware
TCP/IP protocols: TCP, UDP, ICMP, IGMP, IPv4, ARP, IGMP, PPPoE and Ethernet ^^ SPI (Serial Peripheral Interface) provides an interface for easy connection with external MCU. W5500 supports SPI interface communication up to 80MHZ ^^ W5500 provides network wake-up and sleep modes, effectively low system power consumption
