LAN9252I PT Devices Electronic

The LAN9252I PT Devices Electronic is a 2/3-port EtherCAT slave controller with dual integrated Ethernet PHYs which each contain a fullduplex 100BASE-TX transceiver and support 100Mbps (100BASE-TX) operation. The LAN9252 supports HP AutoMDIX, allowing the use of direct connect or cross-over LAN cables. 100BASE-FX is supported via an external fiber transceiver.

The LAN9252 includes an EtherCAT slave controller with 4K bytes of Dual Port memory (DPRAM) and 3 Fieldbus Memory Management Units (FMMUs). 

Highlights 

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
