Product Introduction
The LAN9253 is a 2/3 -port EtherCAT SubDevice controller with dual integrated Ethernet PHYs, each containing a full-duplex 100BASE-TX transceiver that supports 100Mbps (100BASE-TX) operation. The LAN9253 supports HP AutoMDIX, allowing the use of direct connect or cross-over LAN cables. EtherCAT P and Signal Quality Index PHY diagnostics are supported.
The LAN9253 includes an EtherCAT SubDevice 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 SubDevice controller also includes 8 SyncManagers to allow the exchange of data between the EtherCAT MainDevice and the local application. Each SyncManager's direction and mode of operation is configured by the EtherCAT MainDevice. Two modes of operation are available: buffered mode or mailbox mode.
