Introduction
W5500 Ethernet Controller
The W5500 is a single-chip Ethernet controller with integrated TCP/IP stack developed by WIZnet. It eliminates the need for external software to handle network protocols, enabling simple and cost-effective Ethernet connectivity for embedded systems.
Core Functions
- Integrated Hardwired TCP/IP Stack: Features a built-in hardware TCP/IP stack supporting key protocols, including TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE. This avoids protocol processing by the host MCU, reducing its workload.
- Dual Network Interfaces: Provides one 10/100 Mbps Ethernet MAC (Media Access Controller) and one PHY (Physical Layer Transceiver), supporting direct connection to twisted-pair cables (Cat5 or higher) without additional network chips.
- Multiple Independent Sockets: Supports up to 8 independent simultaneous sockets (e.g., 8 TCP connections or a mix of TCP/UDP sockets), enabling multi-task network communication such as data transmission and remote control.
- Flexible Host Interfaces: Offers standard SPI (Serial Peripheral Interface) with speeds up to 80 MHz, ensuring easy integration with most MCUs (Microcontrollers) and MPUs (Microprocessors) while saving GPIO pins.
- Low Power Consumption: Includes power-saving modes (e.g., Power-Down and Wake-On-LAN) to reduce energy use, making it suitable for battery-powered embedded devices like IoT sensors.
- Robust Stability & Protection: Integrates ESD (Electrostatic Discharge) protection (up to ±4 kV) and link-loss detection, enhancing reliability in industrial or harsh environments.
Typical Applications
IoT (Internet of Things) Devices: Used in smart sensors (e.g., temperature/humidity sensors, gas detectors), smart meters, and IoT gateways, enabling real-time data upload to cloud platforms via Ethernet.
Industrial Automation: Deployed in PLCs (Programmable Logic Controllers), industrial HMIs (Human-Machine Interfaces), and sensor networks, providing stable network connectivity for remote monitoring and control of production lines.
Consumer Electronics: Integrated into smart home devices (e.g., networked cameras, smart thermostats, and home energy management systems), supporting wired network access for device synchronization and remote operation.
Embedded Monitoring Systems: Applied in video surveillance DVRs (Digital Video Recorders), environmental monitoring stations, and equipment status monitors, enabling high-speed data transmission and remote access.
Retrofit & Low-Cost Projects: Used to add Ethernet functionality to legacy embedded systems (e.g., 8-bit/16-bit MCUs) that lack built-in network capabilities, avoiding the need for upgrading to high-performance MCUs.
