W5500 LQFP-48 7x7mm WIZnet Ethernet Controller IC

Product Overview

A hardwired TCP/IP embedded Ethernet controller that provides an easier Internet connection to embedded systems. It enables users to implement Internet connectivity in their applications using a single chip with an integrated TCP/IP stack, 10/100 Ethernet MAC, and PHY.

Core Specifications

• Manufacturer: WIZnet Co., Ltd.

• Package Type: 48-pin LQFP

• Function: Hardwired TCP/IP Embedded Ethernet Controller

• Communication Channels: 8 Independent Hardware Sockets Simultaneously

• Control Interface: SPI (Serial Peripheral Interface) supporting up to 80 MHz clock speed

Key Features

• Hardwired Protocol Stack: Market-proven protocol processing engine supporting TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols completely in hardware.

• Internal Buffer Memory: Embeds a 32 Kbyte internal memory buffer dedicated to flexible Ethernet packet processing across the active communication channels.

• Efficient Host Interface: Utilizes a highly efficient SPI protocol for high-speed network communication, simplifying integration with external microcontrollers.

• Power Management: Includes specialized low-power operation modes, offering Wake on LAN (WOL) over UDP and a deep power-down mode to lower system energy consumption.

• Integrated PHY Layer: Houses a complete 10BaseT/100BaseTX Ethernet physical layer that supports auto-negotiation and auto-MDIX correction for stable link configurations.
