WIZwiki Platform

WIZnet WIZwiki Platform based on WIZnet's MCU. WIZnet WIZwiki-W7500P is a WIZwiki platform board based on W7500P. The IOP4IoT W7500P chip is the one-chip solution which integrates an ARM Cortex-M0, 128KB Flash, hardwired TCP/IP core for various embedded application platforms, 10/100 Ethernet MAC and PHY, and especially internet of things. The TCP/IP core is a market-proven hardwired TCP/IP stack and PHY is IC plus IP101G, an IEEE 802.3/802.3u Fast Ethernet Transceiver for 10/100Mbps. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for more than 15 years. W7500P best suits users who need Internet connectivity.
