WIZwiki-W7500ECO is a SoC platform board based on the W7500 chip = ARM Cortex-M0 that integrates 128KB Flash and hardwired TCP/IP core. If you use WIZwiki-W7500 board, you can easily evaluate the W7500 and test its performance and all functions.


WIZnet WIZwiki Platform based on WIZnet's W7500 MCU. The IOP4IoT "Internet Offload Platform for IoT" W7500 chip is the SoC one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application especially for Internet of things and Gateways. The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC. If you use WIZwiki-W7500ECO you will be able to easily develop a prototype. This is using the CMSIS-DAP USB and ISP Header for easy firmware writing in the mbed.org compiler environment.

  • WIZnet W7500ECO
    • ARM® Cortex™-M0 Core 48MHz
    • 128KB Flash memory
    • 16KB to 48 KB SRAM (Min 16KB available if 32KB socket buffer is used, Max 48KB available if no socket buffer is used)
    • Hardwired TCP/IP Core (8 Sockets, MII: Medium-Independent Interface)
    • 12-bit, 8ch ADC
    • 27 I/Os
    • 1ch Watchdog, 4ch Timers and 8ch PWM
    • 3ch UART
    • 2ch SPI
    • 2ch I2C
  • CMSIS-DAP interface firmware
    • Built-in USB drag 'n' drop FLASH programmer
    • USB Virtual COM port for serial terminal
    • CMSIS-DAP interface for programming and debugging from offline tools
  • mbed.org Developer Website
    • Online Compiler
    • High level C/C++ SDK
    • Active developer community


  • You must do not use PWM1, DUALTIMER 0(already used us ticker in mbed driver ).
  • Due to low demand, Dual Edge Triggered GPIO will not be supported.
  • InterruptIn class’ rise() or fall() member function will override the previous callback setting.
  • As a problem with online compilers, OS 2.0 users are encouraged to replace them with OS 5.0 as shown below. /media/uploads/jcm931213/os5_import.png
  • If you want using Ethernet function with mbed OS 5.0 refer to this link : https://os.mbed.com/teams/WIZnet/code/WIZnetInterface-OS5/
