Review - WIZnet WIZwiki-W7500
The WIZwiki-W7500 board is a rapid prototyping platform for IoT and secure networking applications. It is based on the WIZnet W7500 chip that integrates a 32-bit ARM Cortex-M0 core, 128 KB Flash memory and a hardwired TCP/IP stack. Also in the chip is 16 KB RAM (+ 32 KB for the TCP/IP stack that can be added to the system RAM), an MII Interface (for an Ethernet PHY chip), 53 GPIO ports, an 8-channel ADC, three UARTs, two SPI ports and two I²C ports. The TCP/IP stack has an integrated Ethernet MAC and handles the protocols TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE.
