Quick Overview

3 in 1 Fully Hardwired Highspeed (up to 80 Mbps) Ethernet Controller (TCP/IP, MAC, PHY) with DMA connectivity


Fully Hardwired Highspeed TCP/IP Performance

Product Description

The W5300 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems that required high network performance.

W5300 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been proven through various applications over many years. W5300 uses a 128 kBytes internal buffer as its data communication memory.

By using W5300, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller. It is possible to use 8 independent hardware sockets simultaneously. Bus (Direct & Indirect) is provided for easy integration with the external MCU. The W5300 supports max. 80Mbps network throughput.


  • 100LQFP lead-free package (14x14mm)
  • Hardwired TCP/IP protocols : TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
  • Un-attackable hardware network engine for preventing network attacks such as flooding, spoofing, injection
  • Host Interface : 8/16 bit Data Bus (Direct & Indirect Address Mode)
  • High Network Performance : Max 80Mbps (by DMA)
  • Supports embedded OS driver : Linux (kernel 2.6.24)
  • 8 Independent hardware socket
  • Internal 128 kBytes memory for TCP/IP packet processing
  • 10BaseT / 100Base TX Ethernet PHY Embedded
  • Supports Auto-Negotiation (Full & Half Duplex, 10 & 100 Based)
  • Supports Auto-MDIX
