Description
W5100 is a hardwired TCP/IP stack internet controller chip with WIZnet technology, which enables easy internet connectivity to an external MCU via SPI or Parallel System BUS. The SPI interface supports up to 70MHz clock speed, and the Parallel System BUS offers higher communication performance compared to SPI. With an embedded Ethernet MAC and PHY, W5100 allows simple Ethernet application development using socket programming.
