What's inside WIZnet

  1. Overview of ioShield-A Ethernet Shield

    The ioShield-A is an Ethernet shield that allows Arduino boards to connect to the Internet. It is based on the WIZ550io network module and the WIZnet W5500 ethernet chip. The W5500 provides a hardware TCP/IP stack supporting both TCP and UDP with up to eight simultaneous socket connections.

    Important Note: This product has been discontinued and is not recommended for use in new designs.

  2. Overview of the WIZnet TCP/IP Core Offload Engine (TOE)

    The TCP/IP Core Offload Engine (TOE) is a hardwired TCP/IP embedded Ethernet controller designed to simplify Internet connectivity for embedded systems. It offloads the TCP/IP stack from the main CPU, allowing developers to implement network applications using simple socket programming.

    Key capabilities include:

    • Support for protocols: TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE.
    • 8 independent hardware sockets that can operate simultaneously.
    • Integrated 32KB internal memory buffer for TX/RX packet processing.
    • Wake on LAN (WOL) support over UDP to reduce system power consumption.
    • Power down mode for energy efficiency.
    • Note: The TOE does not support IP Fragmentation.

  4. Overview of WIZS2E Config Tool

    The WIZS2E Config Tool is a Windows-based configuration software compatible with WIZ-DTU, WIZ-IP32, W5500S2E, and W7500S2E series serial-to-Ethernet modules. It allows users to search for modules on a local area network (LAN), view current settings, and modify module configurations. To ensure successful connectivity, it is recommended to disable the system firewall and verify that there are no IP address conflicts on the LAN before starting configuration.

  5. Overview of the ARM Cortex-M0 SysTick Timer

    The SysTick timer is a 24-bit timer integrated into the ARM Cortex-M0 core and clocked internally by the system clock. It provides a standardized timer across Cortex-M0 based devices, simplifying software porting. Its primary purpose is to generate fixed-interval interrupts (e.g., 10ms) for operating systems or system management software.

  7. Overview of W5500CoB ESoPe Plug-In Module

    The W5500CoB is a small "Connector-on-Board" plug-in module manufactured by ESoPe. It features a W5500 Ethernet chip and is designed with a breadboard-friendly footprint using 8-pin 100mil distanced pin-headers. The module provides free access to the W5500's SPI and PHY interfaces and includes a vertical RJ45 connector for top-side connectivity.

  11. Overview of WIZnet Network IO Modules

    WIZnet Network IO modules integrate an iEthernet chip and a MAG-JACK (RJ45 with integrated transformer). These modules are designed for rapid development of internet-enabled systems by eliminating the need for manual interfacing between the iEthernet chip and the transformer.
