W5500 Datasheet Version 1.0.7 W5500 The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. WIZnets Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. If you use W5500, you can implement the Ethernet application just by adding the simple socket program. Its faster and easier way rather than using any other Embedded Ethernet solution. Users can use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500s SPI supports 80 MHz speed and new efficient SPI protocol for the high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and power down mode.
