The W5100S chip is a cost-effective embedded Internet controller featuring a full hardwired TCP/IP stack based on WIZnet technology. It enables internet connectivity through either SPI or Parallel System BUS, supporting up to 70MHz clock speed on SPI for seamless connection to external MCUs. This chip integrates a 10/100 Ethernet MAC and PHY, providing a single-chip solution for reliable internet access. It supports major TCP/IP protocols and offers 4 independent sockets along with 16KB of internal memory for efficient data handling. The W5100S facilitates easy Ethernet application development with its simple SOCKET programming, includes energy-saving features like WOL and Power Down Mode, and is backward compatible with W5100 firmware. Available in 48 Pin LQFP and QFN Lead-Free packages, the W5100S is designed for embedded systems requiring stable and low-cost internet connectivity.
