W7500P
Overview

The IOP (Internet Offload Processor) W7500P  is the one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core & PHY for various embedded application platform especially requiring ‘Internet of things’.

The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for years. W7500P suits best for users who need Internet connectivity for application.
