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.
WIZnet‘s 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. It’s
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 W5500’s 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.
