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.","working_principle":"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.","pin_description":"
