WIZ-IP55 User Manual1 Introduction 1.1 Overview WIZ-IP55 is a network offloading module that integrates the W5500 chip (with built-in PHY physical layer and TCP/IP hardware protocol stack) and an RJ45 connector with integrated network transformer. As a plug-and-play component, it enables seamless interface connection between the W5500 and the transformer without the need for additional circuit design. For users who wish to quickly develop networked systems, WIZ-IP55 is an ideal choice. Note:For detailed information on the hardware TCP/IP protocol stack, please refer to W5500 Data Sheet. The WIZ-IP55 module is composed as follows: ⚫ Network port connector section: Integrated network transformer network port (including W5500 chip, network transformer and RJ45). ⚫ TCP/IP protocol stack and Ethernet MAC: Implemented by W5500 chip. ⚫ Ethernet PHY: Integrated by W5500 chip. 1.1.1 Functional Features ⚫ Supports full hardware TCP/IP protocol: TCP, UDP, WOL, ICMP, IGMPv1/v2, IPv4, ARP, PPPoE ⚫ Supports 8 independent SOCKET concurrent communication ⚫ Supports half-duplex/full-duplex operation mode ⚫ Supports Ethernet power-off mode ⚫ Supports UDP-based network wake-up (WOL) function ⚫ High-speed SPI interface (MODE 0/3) ⚫ Built-in total 32Kbytes of send/receive cache ⚫ Integrated 10BaseT/100BaseTX Ethernet PHY ⚫ Supports Ethernet auto negotiation (full/half-duplex,10Base-T/100Base-TX) ⚫ Operating voltage:3.3V (I/O compatible with 5V signal voltage) ⚫ 19-pin pin header interface ⚫ Package size (length×width×height):32.5×16.5×17.3(mm) ⚫ Compatible with WIZnet's IO module carrier board development board WIZ-IP55 User Manual3 / 10
