W6100 is ready for IPv6

With the enormous growth of IoT devices connected to the networking, it became evident that far more addresses would be needed to connect devices than the IPv4 address space had available. Wiznet has a solution.

Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP). It is the communication protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.

The new W6100 chip from Wiznet solves the problem with the lack of IP addresses in IPv4.

It supports IPv4/IPv6 dual stack by adding IPv6 functions on the basis of WIZnet’s patented hardwired TCP/IP core technology. W6100 supports TCP/IP protocols such as TCP, UDP, IPv6, IPv4, ICMPv6, ICMPv4, IGMP, ARP and PPPoE. W6100 also includes 10Base-T/10Base-Te/100Base-TX Ethernet PHY and Ethernet MAC Controller which makes it suitable for embedded internet-enabled devices.

W6100 is ready for IPv6

W6100 has 8 independent hardwired SOCKETs and supports various SOCKET-less commands, which are for IPv6 auto-configuration, monitoring, and managing the network via ARP, PINGv4, and PINGv6. It supports two kinds of HOST interfaces; SPI and parallel system BUS. It has 32KB internal memory for sending and receiving data.

It is designed for low power and low self-heating, W6100 provides WOL (Wake On LAN), Ethernet PHY power down mode, etc. W6100 comes in two packages, 48 LQFP, and 48 QFN; both are lead-free and these versions are PIN-2-PIN compatible with W5100S, which is a great advantage for easy migration from the older chip.
