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
