LAN9255

Microchip’s LAN9255 is an EtherCAT device controller (ESC) with Cortex M4F Microcontroller.

EtherCAT functionality is delivered together with dual PHYs which each provide a full-duplex 100BASE-TX transceiver and support 100Mbps (100BASE-TX) operation. The LAN9255 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 3 port EtherCAT device controller provides 8K bytes of Dual Port memory (DPRAM), 8 SyncManagers, 8 Fieldbus Memory Management Units (FMMUs) and a 64-bit Distributed Clock.

A CortexM4F controller provides a suite of peripherals including Ethernet MAC. Customers can realize multiprotocol designs in the knowledge all items are supported within the MPLABX Harmony Framework

The LAN9255 is available in commercial, industrial and extended industrial temperature ranges and is packaged in 128 pin TQFP.
