The IOP4IoT W7500 chip is the one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application platform especially internet of things.
The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 802.3 10/100 Ethernet MAC with PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE which has been proven through various applications over many years. W5500 uses a 32Kbytes internal buffer as its data communication memory.
