This chip is a one-chip solution with an embedded 10\/100 Ethernet MAC and PHY, and it supports various protocols like TCP, UDP, and IPv4. Furthermore, it provides 8 independent SOCKETs and 32KB of internal memory, enabling the development of Ethernet applications simply by using the SOCKET program. It also reduces power consumption through WOL (Wake on LAN) and a Power Down Mode.<\/span><\/strong><\/p>\n<hr \/>\n<h2>Features<\/h2>\n<ul>\n<li><strong><span style=\"font-size: 14px;\">Supports following Hardwired TCP\/IP Protocols : TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Supports 8 independent sockets simultaneously<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Supports Power down mode<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Supports Wake on LAN over UDP<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Supports High Speed Serial Peripheral Interface(SPI MODE 0, 3)<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Internal 32Kbytes Memory for Tx\/Rx Buffers<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">10BaseT\/100BaseTX Ethernet PHY embedded<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Support Auto Negotiation (Full and half duplex, 10 and 100-based)<\/span><\/strong><\/li>\n<li><span style=\"font-size: 14px; color: #ff0000;\"><strong>Not support Auto MDI\/MDIX<\/strong><\/span><\/li>\n<li><strong><span style=\"font-size: 14px;\">Not support IP Fragmentation<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">3.3V operation with 5V I\/O signal tolerance<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">LED outputs (Full\/Half duplex, Link, Speed, Active)<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">48 Pin LQFP Lead-Free Package (7x7mm, 0.5mm pitch)<\/span><\/strong><\/li>\n<\/ul>\n<h2>Documents<\/h2>\n<ul>\n<li><strong><span style=\"font-size: 14px;\">Datasheet(<a href=\"https:\/\/docs.wiznet.io\/assets\/files\/W5500_ds_v110k-8a79ea6cf98a804f93c7deb2398cb53f.pdf\">KOR<\/a>\/ <a href=\"https:\/\/docs.wiznet.io\/assets\/files\/W5500_ds_v110e-226ffec190c588b69f88d629789585e1.pdf\">ENG<\/a>)<\/span><\/strong><\/li>\n<li><strong><span style=\"font-size: 14px;\">Reference Schematic(<a href=\"https:\/\/docs.wiznet.io\/assets\/files\/w5500_sch_v110_use_trans_-18b3297138bdf20fafd0f95e4c19358d.pdf\">Transformer<\/a> \/ <a href=\"https:\/\/docs.wiznet.io\/assets\/files\/w5500_sch_v110_use_mag_-dfff8bbb103d13be4f25cd2b2f8b950d.pdf\">RJ45<\/a>)<\/span><\/strong><\/li>\n<\/ul>\n<h2>Driver<\/h2>\n<ul>\n<li><a href=\"https:\/\/github.com\/Wiznet\/ioLibrary_Driver\"><strong><span style=\"font-size: 14px;\">ioLibrary_Driver<\/span><\/strong><\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p><strong><span style=\"font-size: 14px;\">Fast Ethernet based IC supporting up to 8 sockets<\/span><\/strong><\/p>\n<p><strong><span style=\"font-size: 14px;\">A flagship IC from WIZnet, selling nearly 10 million units per year<\/span><\/strong><\/p>\n<p><span style=\"font-size: 14px; color: #ff0000;\"><strong>Cannot be used with products that require Auto-MDIX<\/strong><\/span><\/p>\n<p>&nbsp;<\/p>","protected":false},"featured_media":1979,"comment_status":"open","ping_status":"closed","template":"","meta":{"_themeisle_gutenberg_block_has_review":false},"product_brand":[124],"product_cat":[132,129,130],"product_tag":[135,138],"class_list":{"0":"post-1964","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-wiznet","7":"product_cat-8-sockets","8":"product_cat-ic","9":"product_cat-phy-embedded","10":"product_tag-tcp-ip-chip","11":"product_tag-w500","13":"first","14":"instock","15":"taxable","16":"shipping-taxable","17":"purchasable","18":"product-type-simple"},"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product\/1964","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/comments?post=1964"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/media\/1979"}],"wp:attachment":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/media?parent=1964"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_brand?post=1964"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_cat?post=1964"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_tag?post=1964"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
