LAN9253 EtherCAT® Device Controller

Microchip Technology LAN9253 EtherCAT® Device Controller provides dual-integrated Ethernet PHYs, each of which provides a full-duplex 100BASE-TX transceiver and supports 100Mbps operation. The LAN9253 supports HP Auto-MDIX, allowing the use of direct-connect or cross-over LAN cables. This device provides system developers a cost-effective solution for realizing EtherCAT device solutions. The LAN9253 includes a 3-port EtherCAT slave controller with 8K bytes of Dual Port memory (DPRAM), 8 SyncManagers, 8 Fieldbus Memory Management Units (FMMUs), and a 64-bit Distributed Clock.
