WIZnet W5300

Produktbeschreibung

WIZnet's W5300 is a tiny CMOS-based single chip with integrated 10/100 Ethernet controller, MAC, and TCP/IP. The W5300 is designed for Internet embedded applications where easy implementation, stability, high performance, and effective cost are required. The chip is packed with features, and can be used in a number of embedded applications including home-network devices, serial-to-ethernet, USB-to-ethernet, security systems, building automation, embedded servers and more.

Features:

• Supports hardwired TCP/IP protocols : TCP,UDP, ICMP, IPv4, ARP, IGMPv2, PPPoE, Ethernet
  
• Supports 8 independent SOCKETs simultaneously
  
• High network performance : Up to 80Mbps (DMA)
  
• Supports hybrid TCP/IP stack(software and hardware TCP/IP stack)
  
• IP Fragmentation is not supported
  
• Internal 128Kbytes memory for data communication(Internal TX/RX memory)
  
• More flexible allocation internal TX/RX memory according to application throughput
  
• Supports memory-to-memory DMA (only 16bit Data bus width & slave mode)
  
• Embedded 10BaseT/100BaseTX Ethernet PHY
  
• Supports auto negotiation (Full-duplex and half duplex)
  
• Supports auto MDI/MDIX(Crossover)
  
• Supports network Indicator LEDs (TX, RX, Full/Half duplex, Collision, Link, Speed)
  
• Supports a external PHY instead of the internal PHY
  
• Supports 16/8 bit data bus width
  
• Supports 2 host interface mode(Direct address mode & Indirect address mode)
  
• External 25MHz operation frequency (For internal PLL logic, period=40ns)
  
• Internal 150MHz core operation frequency (PLL_CLK, period=about 6.67ns)
  
• Network operation frequency (NIC_CLK : 25MHz(100BaseTX) or 2.5MHz(10BaseT))
  
• 3.3V operation with 5V I/O signal tolerance
  
• Embedded power regulator for 1.8V core operation
  
• 0.18 µm CMOS technology
  
• 100LQFP 14X14 Lead-Free Package
