Connect your 8-bit MCU to an Ethernet Network
The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier Internet connection for embedded systems using SPI (Serial Peripheral Interface).

It includes TCP/IP Stack, 10/100 Ethernet MAC and PHY. Unlike most other solutions, the TCP/IP protocol is implemented directly in the HW in the chip and supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE protocols.

The W5500 uses an internal buffer with a capacity of 32kB as its data communication memory.
