Product Introduction
The LAN9254 is a 2/3-port EtherCAT slave controller with dual integrated Ethernet PHYs, each containing a full-duplex 100BASE-TX transceiver that supports 100Mbps (100BASE-TX) operation. The LAN9254 supports HP Auto-MDIX, allowing the use of direct connect or cross-over LAN cables. EtherCAT P and Signal Quality Index PHY diagnostics are supported.
The LAN9254 includes an EtherCAT slave controller with 8K bytes of Dual Port memory (DPRAM) and 8 Fieldbus Memory Management Units (FMMUs). Each FMMU performs the task of mapping logical addresses to physical addresses. The EtherCAT slave controller also includes 8 SyncManagers to allow the exchange of data between the EtherCAT master and the local application. Each SyncManager's direction and mode of operation is configured by the EtherCAT master. Two modes of operation are available: buffered mode or mailbox mode. In the buffered mode, both the local microcontroller and EtherCAT master can write to th
