IOP (Internet Offload Processor) W7500은 특히 “사물인터넷”을 요구하는 다양한 임베디드 어플리케이션 플랫폼을 위해 ARM Cortex-M0, 128KB 플래시, Hardwired TCP/IP 코어 와 PHY 등이 하나의 칩에 통합되어 있습니다. TCP/IP 코어는 통합된 이더넷 MAC을 포함한 마켓에서 증명된 Hardwired TCP/IP 스택 입니다. 이 Hardwired TCP/IP 스택은 수많은 어플리케이션에 오랜 기간 걸쳐 사용되어 오고 있으며 TCP, UDP, IPv4, ICMP, ARP, AGMP, PPPoE 등을 지원합니다. W7500은 인터넷 연결을 필요로 하는 어플리케이션 사용할 수 있도록 특별히 최적화된 제품입니다.
