WIZnet’s iEthernet ICs include 10/100 Ethernet MAC and PHY with hardwired TCP/IP – that can be used for Ethernet with as small as an 8bit MCU. The patented hardwired TCP/IP technology lessens the MCU workload and amount of coding that will fasten the user’s development process. WIZnet‘s IC s have been used in Arduino’s official Ethernet shield 1, 2, and also the latest Arduino Ethernet MKR ETH shield. Our hardwired TCP/IP stack supports TCP, UDP, IPv4, IPv6, ICMP, ARP, IGMP, and PPPoE – which has been proven from various application over the past 15 years.
・ Supports TCP/IP Protocols : TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE ・ Supports 4/8 independent sockets simultaneously ・ Supports Power down mode ・ Supports Wake on LAN over UDP ・ Supports High Speed Serial Peripheral Interface(SPI MODE 0, 3) ・ Supports 8 & 16 Bits Bus interfaces
・ Internal Memory for Tx/Rx Buffers ・ 10BaseT/100BaseTX Ethernet PHY embedded ・ Support Auto Negotiation (Full and half duplex, 10 and 100-based) ・ Not support IP Fragmentation ・ 3.3V operation with 5V I/O signal tolerance
