Quick Overview

3 in 1 chip for the Internet connectivity
Hardwired TCP/IP + MAC + PHY
Both SPI and parallel bus Interface 48QFN


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

Product Description

The W6100 is a Hardwired TCP/IP embedded Ethernet Controller that enables easier Internet Connection for embedded Systems using SPI (Serial Peripheral Interface) and Parallel Bus that incorporates IPv6 and is pincompatible to W5100S

W6100 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. W6100 uses a 16 Kbytes Internal Buffer as its Data Communication Memory.

By using W6100, 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 8 independent hardware sockets simultaneously. 

W6100 users can implement High-Speed Network Communication. In order to reduce the power consumption of the system, W6100 provides a Power Down mode and can be enabled by Wake On Lan.

Information for users of the W6100: The new W6100 and 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 W6100/W5100S without any modification.
