KSZ9477STXI-TR

The KSZ9477STXI-TR from Microchip is a 7 port Gigabit Ethernet switch with ring redundancy, SGMII and RGMII/MII/RMII interfaces in 128-pin TQFP-EP package. The KSZ9477S is built upon industry-leading Ethernet technology, a highly integrated, IEEE 802.3 compliant networking device that incorporates a layer-2 managed Gigabit Ethernet switch, five 10BASE-Te/100BASE-TX/1000BASE-T physical layer transceivers (PHYs) and associated MAC units and two individually configurable MAC ports (one SGMII interface, one RGMII/MII/RMII interface) for direct connection to a host processor/controller, another Ethernet switch or an Ethernet PHY transceiver. It is used in industrial Ethernet (Profinet, MODBUS, Ethernet/IP), real-time Ethernet networks, IEC 61850 networks w/ power substation automation, industrial control/automation switches, networked measurement and control systems.
