Product Overview
The SDEE-ETH is a hardware TCP/IP embedded Ethernet controller module designed by our company based on the W5500 chip, providing a simpler internet connectivity solution for motherboards. The module integrates a TCP/IP protocol stack, 10/100 Ethernet MAC and PHY, communicates with an external MCU via a SPI interface, supports high-speed SPI communication up to 80 MHz, and includes Wake-on-LAN (WOL) and power-down modes to reduce system power consumption.
Embedded hardware TCP/IP protocol stack supporting TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE.
Embedded 10BaseT/100BaseTX Ethernet PHY supporting auto-negotiation (full-duplex/half-duplex, 10M/100M);
High-speed SPI interface (supports Mode 0/3), up to 80 MHz, guaranteed stable communication at minimum 33.3MHz.
3 V operating voltage, 5 V I/O tolerance, supports WOL network wake-up and Power Down mode;
Compact, lightweight, and easy to install.
