The LAN9253-I/R4X from Microchip is a 2/3-port EtherCAT slave controller with dual integrated 100BASE-TX PHYs. It provides 8K DPRAM, 8 FMMUs, 8 SyncManagers, and a 64-bit distributed clock. Multiple host interfaces (SPI/SQI, HBI, Digital I/O) support various MCU architectures. The -I grade supports industrial temperature range -40 to 85C.

The LAN9253 implements the EtherCAT slave protocol stack in hardware. The ESC processes EtherCAT frames passing through the daisy-chained ports, extracting and inserting process data via FMMUs and SyncManagers. The host MCU accesses DPRAM through SPI/SQI (low pin count) or HBI (high bandwidth). In Digital I/O mode, 16 I/O signals are directly controlled by the EtherCAT master without an MCU.
