W5100S-L

Product Description

Hardware TCP/IP Performance and Ease of Use to Low-Cost ‘IoT’ Applications

The W5100S is a Hardwired TCP/IP embedded Ethernet Controller that enables easier Internet Connection for embedded Systems using SPI (Serial Peripheral Interface) and Parallel Bus. 

W5100S suits users in need of stable Internet Connectivity Best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC, and PHY. The implemented Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE which has been proven through various Applications over many years. W5100S uses a 16 Kbytes Internal Buffer as its Data Communication Memory.

By using W5100S, 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 4 independent hardware sockets simultaneously. 

The W5100S SPI supports up to 70 MHz speed and the new efficient SPI Protocol, so users can implement High-Speed Network Communication. In order to reduce the power consumption of the system, W5100S provides a Power Down mode and can be enabled by Wake On Lan.

Information for users of the W5100: The new W5100S is not fully pin-to-pin compatible with the W5100, but the software compatibility is kept, hence the software for the W5100 can be used with the W5100S without any modification.
