Description:
The Microchip LAN9252 is a 2/3-port EtherCAT® Slave Controller (ESC) with dual integrated Ethernet PHYs. The LAN9252 is typically implemented in Industrial Automation solutions and includes the following main features: ? Integrated high-performance 100Mbps Ethernet transceivers ? 3 FMMUs, 4 SyncManagers, Distributed clock support, 4K bytes of DPRAM ? 8/16-bit host bus interface allowing connection to most 8/16/32-bit embedded controllers ? SPI / SQI slave interface ? Support for 5 different main configurations: - Digital I/O (DIGIO) - HBI - SPI with GPIO - SPI with MII - 3-port (MII upstream) mode - SPI with MII - 4-port (MII downstream) mode ? 3rd port for flexible network configurations ? Comprehensive power management features ? Low pin count and small package size The purpose of this document is to provide details on the various LAN9252 EEPROM configuration and programming options when using the EVB-LAN9252-HBI and EVB-LAN9252-DIGIO evaluation boards.
