    W5100 

    • All-in-one Ethernet Controller : Hardware TCP/IP, MAC & PHY
    • Fully hardwired network protocol 
    • Direct & Indirect Bus and SPI for Host Interface
    • Stable Data Communication

    The W5100 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier Internet connection for embedded systems.

    W5100 suits users in need of stable Internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years. W5100 uses a 16ytes internal buffer as its data communication memory.

    By using W5100, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller.

    It is possible to use 4 independent hardware sockets simultaneously. BUS (Direct  & Indirect) & SPI (Serial Peripheral Interface) are provided for easy integration with the external MCU.

    Key Features of W5100
    • Hardwired TCP/IP protocols : TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
    • Un-attackable hardware network engine for preventing network attacks such as flooding, spoofing, injection
    • Host Interface : Direct/Indirect Bus & Serial Peripheral Interface (SPI MODE 0, 3)
    • 4 Independent hardware socket
    • Internal 16Kbytes memory for TCP/IP packet processing
    • 10BaseT / 100Base TX Ethernet PHY Embedded
    • Support Auto-Negotiation (Full & Half Duplex, 10 & 100 Based)
    • Support Auto-MDIX
    • 3.3V Operation with 5V I/O signal tolerance
    • LED outputs (TX, RX, full/half duplex, Collision, link, speed)
    • 80LQFP lead-free package (10x10mm)
