Product Introduction

The LAN9254 is a 2/3-port EtherCAT slave controller with two integrated Ethernet PHYs, each containing a full-duplex 100BASE-TX transceiver supporting 100Mbps (100BASE-TX) operation. The LAN9254 supports HP Auto-MDIX, allowing the use of straight-through or crossover LAN cables. It supports EtherCAT P and Signal Quality Index PHY diagnostics. The LAN9254 incorporates an EtherCAT slave controller with 8K bytes of Dual-Port RAM (DPRAM) and 8 Fieldbus Memory Management Units (FMMUs). Each FMMU performs logical-to-physical address mapping. The EtherCAT slave controller also includes 8 Sync Managers to facilitate data exchange between the EtherCAT master and local applications. The direction and operating mode of each Sync Manager is configured by the EtherCAT master. Two operating modes are available: Buffered Mode or Mailbox Mode. In Buffered Mode, both the local microcontroller and the EtherCAT master can perform write operations.

Features
