描述 Description

Fully hardwired network protocol
High Speed SPI for Host Interface
Compact Size : 48QFN Lead-free package (7x7mm)
Stable Data Communication
The W5200 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier Internet connection for embedded systems.

W5200 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. W5200 uses a 32Kbytes internal buffer as its data communication memory.

By using W5200, 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 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. In order to reduce power consumption of the system, W5200 provides WOL (Wake on LAN) and a power down mode.
