Description

The W5500 chip is a Hardwired Internet controller designed as a full hardwired TCP/IP stack with WIZnet technology. W5500 provides Internet connectivity to your embedded systems by using SPI(Serial Peripheral Interface). SPI provides easy connection via external MCU to W5500. The clock speed of W5500 SPI supports upto 80MHz. Since W5500 integrates the Hardwired TCP/IP stack with 10/100 Ethernet MAC and PHY, it is truly a one-chip solution for the stable internet connectivity. WIZnet's Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE - and it has been proven through various applications over the last decade. W5500 provides 8 independent SOCKETs to be used simultaneously and 32KB internal memory for data communication. Users can develop an Ethernet application easily by using the simple W5500 SOCKET program instead of handling a complex Ethernet controller. W5500 also provides WOL (Wake on LAN) and a Power Down Mode in order to reduce power consumption.
