auto-negotiation and auto-MDI/MDIX. It also supports 6 network indicator LED outputs such as

TCP/IP Engine
TCP/IP Engine is a hardwired logic based network protocol which contains technology of
- TCP(Transmission Control Protocol)
- UDP(User Datagram Protocol)
- ICMP(Internet Control Message Protocol)
- IGMPv1/v2(Internet Group Management Protocol version 1/2)
- PPPoE(Point-To-Point Protocol over Ethernet)
- ARP(Address Resolution Protocol)
- IP (Internet Protocol)
- 802.3 Ethernet MAC(Media Access Control)
Ethernet PHY
The W7200 includes 10BaseT/100BaseTX Ethernet PHY. It supports half-duplex/full-duplex,
This protocol operates in the TCP layer and provides data communication. Both TCP
server and client modes are supported.
It is a protocol which supports data communication at the UDP layer. User datagram
such as unicast, multicast, and broadcast are supported
ICMP is a protocol which provides information, unreachable destination. When a
Pingrequest ICMP packet is received, a Ping-reply ICMP packet is sent.
This protocol processes IGMP messages such as the IGMP Join/Leave. The IGMP is only
enabled in UDP multicast mode. Only version 1 and 2 of IGMP logic is supported. When
using a newer version of IGMP, IGMP should be manually implemented in the IP layer.
This protocol uses PPP service over Ethernet. The payload (PPP frame) is encapsulated
inside an Ethernet frame during a transmission. When receiving, it de-capsulates the
PPP frame. PPPoE supports PPP communication with PPPoE server and PAP/CHAP
authentications.
ARP is the MAC address resolution protocol by using IP address. This protocol exchanges
ARP-reply and ARP-request from peers to determine the MAC address of each other
This protocol operates in the IP layer and provides data communication. IP
fragmentation is not supported. It is not possible to receive the fragmented packets. All
protocol number is supported except for TCP or UDP. In case of TCP or UDP, use the
hardwired embedded TCP/IP stack.
This controls Ethernet access of CSMA/CD(Carrier Sense Multiple Access with Collision
Detect). The protocol is based on a 48-bit source/destination MAC address.
