W5100S-L Description

Short technical summary and product information.

The WIZnet W5100S-L is an embedded Internet Controller Chip designed with Hardwired TCP/IP technology. It provides a one-chip solution for Internet connectivity, supporting IPv4, TCP, UDP, ICMP, IGMP, ARP, and PPPoE protocols. The chip integrates an Ethernet MAC and a 10Base-T/100Base-TX Ethernet PHY.

 

Key features include support for 4 independent sockets simultaneously, a SPI and Parallel System BUS interface, and internal 16KB memory for transmit and receive buffers. It operates at 3.3V with 5V I/O signal tolerance and has an operating temperature range of -40°C to 85°C. The W5100S-L is available in a 48-LQFP package.

 

This controller is well-suited for various embedded applications, including home network devices, serial-to-Ethernet converters, security systems, and IoT devices. Its low-power and low-heat design, along with features like Wake on LAN (WOL) and Ethernet PHY Power Down Mode, make it an efficient choice for product miniaturization and power saving.
