W5500 EVB Rev1.0


W5500 EVB is an evaluation board for W5500 chip based on the 32-bit ARM® Cortex™-M0 microcontroller. It is the easy way to develop internet connection for efficient and small embedded systems using W5500, WIZnet's hardwired TCP/IP embedded Ethernet controller. It has been designed to be hardware pin-compatible with 'Arduino shields' for the 'Arduino UNO Rev3' and other footprint-compatible boards.

It is based on the NXP LPC11E36 MCU with a 32-bit ARM® Cortex™-M0 core running at 50MHz. It includes 96kB Flash memory, 12kB SRAM, 4kB EEPROM and various interfaces, including SPI/SSP, I2C, UART, ADC, PWM and other I/O interfaces. Additionally, the on-board temperature sensor / potentiometer is ready for useful ADC control examples. Two programmable push button switches, one RGB LED, an external 4-Mbit serial dataflash memory and a 10/100 Base-Tx RJ-45 connector with an integrated transformer are on board to implement embedded networking applications.

The W5500 EVB provides benefits in developing easier and powerful network applications on small form-factor and non-OS based embedded devices using the W5500 chip.
