LAN9252  
2/3-Port EtherCAT® Slave Controller with  
Integrated Ethernet PHYs  
Highlights  
Key Benefits  
• 2/3-port EtherCAT slave controller with 3 Fieldbus  
Memory Management Units (FMMUs) and  
4 SyncManagers  
• Interfaces to most 8/16-bit embedded controllers  
and 32-bit embedded controllers with an 8/16-bit  
bus  
• Integrated Ethernet PHYs with HP Auto-MDIX  
• Wake on LAN (WoL) support  
• Low power mode allows systems to enter sleep  
mode until addressed by the Master  
• Cable diagnostic support  
• Integrated high-performance 100Mbps Ethernet  
transceivers
