Product Details

LAN9252 EtherCAT® Slave Controllers

The LAN9252 device from Microchip is a 2/3 port EtherCAT® slave controller with dual integrated Ethernet PHYs, each of which contain a full-duplex 100BASE-TX transceiver. The LAN9252 supports HP Auto MDI-X that allows the use of direct connect or cross-over LAN cables. 100BASE-FX is supported via an external fiber transceiver. Included is a 3 port EtherCAT® slave controller with 4K bytes of Dual Port memory (DPRAM), 4 SyncManagers, 3 Fieldbus Memory Management Units (FMMUs) and a 64-bit Distributed Clock. The LAN9252 supports 4 Process Data Interfaces - SPI/SQI, HBI and a 16 Bit Digital IO.
