WIZnet ARM Cortex M3 iMCU W7200 & Evaluation Board

WIZnet ARM Cortex M3 iMCU W7200 & Evaluation Board

WIZnet ARM Cortex M3 Internet Embedded MCU (iMCU) W7200 is a one-chip solution that integrates an ARM 32-bit Cortex-M3 core from STmicro, 20KB SRAM, and a hardwired TCP/IP core for high performance and easy development. The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC & PHY. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE which has been used in various applications for years.

Also available is the W7200-EVB Evaluation Board for testing the iMCU W7200 and for prototyping development. W7200-EVB is composed of a W7200 based on the ARM Cortex M3, which acts as a hardwired TCP/IP embedded Ethernet controller, and a FT232R which acts as USB-to-UART interface IC. The USB-to-UART interface IC in W7200-EVB can be used for UART communication. And the extension pin header (total of 40 pins) allows the user for easy connection and testing. W7200-EVB can provide simple example codes based on ANSI C to implement various internet application programs based on the W5200. Also, the W5200 can be used as a small embedded device in power down mode to save power consumption.
