W5500 Datasheet Version 1.0 © Copyright 2013 WIZnet Co., Ltd. . W5500 The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. W5500 enables users to h e 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 munication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and power down mode. Features - Supports Hardwired TCP/IP Protocols : TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE - Supports 8 independent sockets simultaneously - Supports Power down mode - Supports Wake on LAN over UDP - Supports High Speed Serial Peripheral Interface(SPI MODE 0, 3) - Internal 32Kbytes Memory for TX/RX Buffers - 10BaseT/100BaseTX Ethernet PHY embedded - Supports Auto Negotiation (Full and half duplex, 10 and 100 -based ) - Not
