The SPI interface supports up to 70MHz clock speed, and the Parallel System BUS offers higher communication performance compared to SPI. With an embedded Ethernet MAC and PHY, W5100 allows simple Ethernet application development using socket programming.<\/strong><\/span><\/p>\n<hr \/>\n<h2>Features<\/h2>\n<ul>\n<li><span style=\"font-size: 14px;\"><strong>Support Hardwired Internet Protocols: TCP, UDP, WOL over UDP, ICMP, IGMPv1\/v2, IPv4, ARP, PPPoE<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support 4 Independent Hardware SOCKETs simultaneously<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support SOCKET-less Command: ARP-Request, PING-Request<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support Ethernet Power Down Mode &amp; Main Clock gating for power save<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support Wake on LAN over UDP<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support Serial &amp; Parallel Host Interface: High Speed SPI(MODE 0\/3), Parallel System Bus with 2 Address signal &amp; 8bits Data<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Internal 16 Kbytes Memory for TX\/ RX Buffers<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Not support IP Fragmentation<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Not Maintain ARP-cache Table<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>10BaseT\/100BaseTX Ethernet PHY Integrated<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support Auto Negotiation (Full\/Half Duplex, 10\/100 Speed)<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Support Auto-MDIX when Auto-Negotiation Mode.<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>3.3V operation with 5V I\/O signal tolerance<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>LED outputs (Full\/Half Duplex, Link, 10\/100 Speed, Active)<\/strong><\/span><\/li>\n<li><span style=\"font-size: 14px;\"><strong>Two types of packages: 48 Pin LQFP &amp; QFN Lead-Free Package (7x7mm, 0.5mm pitch)<\/strong><\/span><\/li>\n<\/ul>\n<h2>Documents<\/h2>\n<ul>\n<li><a href=\"https:\/\/docs.wiznet.io\/assets\/files\/W5100_DS_V128E-68b8612e5ec92bb4cdf8f53cf6bfb8a9.pdf\">Datasheet<\/a><\/li>\n<li><a href=\"https:\/\/docs.wiznet.io\/assets\/files\/3150Aplus_5100_ES_V260E-fd73c9b1ba893c062c5c00483446f397.pdf\">Errata<\/a><\/li>\n<li><a href=\"https:\/\/docs.wiznet.io\/assets\/files\/w5100_hardware-8cd9c5fe48872508ef1a12a0a5cd2317.zip\">Reference Schematic<\/a><\/li>\n<\/ul>\n<h2>Driver<\/h2>\n<ul>\n<li><a href=\"https:\/\/github.com\/Wiznet\/ioLibrary_Driver\">Driver<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p><strong><span style=\"font-size: 14px;\">Fast Ethernet based IC supporting 4 sockets<\/span><\/strong><\/p>","protected":false},"featured_media":1976,"comment_status":"open","ping_status":"closed","template":"","meta":{"_themeisle_gutenberg_block_has_review":false},"product_brand":[124],"product_cat":[131,129,130],"product_tag":[134,135,133],"class_list":{"0":"post-1960","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-wiznet","7":"product_cat-4-sockets","8":"product_cat-ic","9":"product_cat-phy-embedded","10":"product_tag-4-sockets","11":"product_tag-tcp-ip-chip","12":"product_tag-w5500","14":"first","15":"instock","16":"taxable","17":"shipping-taxable","18":"purchasable","19":"product-type-simple"},"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product\/1960","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=1960"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/media\/1976"}],"wp:attachment":[{"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/media?parent=1960"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_brand?post=1960"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_cat?post=1960"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/twarelab.com\/en\/wp-json\/wp\/v2\/product_tag?post=1960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
