2012-03-30 WIznet's ARM + TCP/IP chip


iMCU W7200 is the one-chip solution which integrates an Cortex-M3 core, 20KB SRAM and hardwired TCP/IP Core for high performance and easy development.
The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC & PHY. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for years
