W5100 TCP / IP SPI Interface Ethernet Network Module - Blue
Description: W5100 is a versatile single-chip network interface module£¬ integrates 10/100Mbps Ethernet controller inside£¬ mainly used in high integration£¬ high stability£¬ high performance and low-cost embedded systems. W5100 can achieve the Internet connection without an operating system. W5100 is compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX. W5100 integrates a full hardware TCP / IP protocol stack£¬ MAC and PHY. Full hardware TCP / IP protocol stack supports TCP£¬ UDP£¬ IPv4£¬ ICMP£¬ ARP£¬ IGMP and PPPoE. W5100 also integrates 16KB of internal memory for data transfer. Don't need to consider Ethernet control£¬ only a simple programming. Features: With the MCU variety of interface options: direct parallel bus interface£¬ indirect parallel bus interface and SPI bus interface; Supports hardware TCP/IP protocol: TCP£¬ UDP£¬ ICMP£¬ IGMP£¬ IPv4£¬ ARP£¬ PPPoE£¬ Ethernet; Supports ADSL connection (supports PPPOE protocol£¬ with PAP / CHAP authentication); Supports 4 separate ports (sockets) connected at the same time; 16K bytes of internal memory for TX/RX buffer; Embedded 10BaseT / 100BaseTX Ethernet physical layer£¬ supports auto answer (full / half duplex mode); Supports auto-polarity (MDI / MDIX); Multiple indicator output (Full/Duplex£¬ Collision£¬ Link£¬ Speed); 3.3V working voltage£¬ the I/O port can withstand 5V voltage.
