Product Description

The IOP4IoT W7500 chip is the one-chip solution which integrates an ARM Cortex-M0 (including 128kB Flash) and the hardwired TCP/IP core for various embedded application platforms, especially for Internet of Things applications. The TCP/IP core is a market-proven hardwired TCP/IP stack (WIZnet W5500) with an integrated Ethernet MAC. The stack supports multiple protocols, including TCP, UDP, ICMP, ARP, IGMP and PPoE. The expertise of more than 15 years of product development has been incorporated into this product.
