Microchip 128-Pin TQFP Ethernet Switch IC 1.8 V to 3.46 V 100 Mbps MII RGMII RMII Full Duplex/Half Duplex KSZ8567RTXI

Microchip KSZ8567RTXI is a highly integrated Ethernet switch IC designed for industrial and commercial networking applications. Packaged in a 128-pin Thin Quad Flat Package (TQFP), this device supports multi-speed data rates up to 100 Mbps using MII, RGMII, and RMII interfaces, facilitating reliable full and half duplex communication modes. Its architecture includes five 10BASE-T/100BASE-TX physical layer transceivers with associated MAC units, enabling the handling of multiple network ports simultaneously.

The device incorporates a layer-2 managed, non-blocking wire-speed Ethernet switch fabric that supports aggregate throughput of 1 Gbps on the RGMII interface. It provides comprehensive forwarding and filtering controls including VLAN and Quality of Service (QoS) capabilities, which enable advanced network traffic management and prioritization based on port ingress/egress queues and traffic classification. These features make it suitable for industrial Ethernet systems demanding real-time communications and network security.

Supporting IEEE 1588v2 precision time protocol (PTP), the KSZ8567RTXI includes hardware time-stamping and a high-resolution hardware clock for sub-microsecond synchronization across system devices, critical for industrial automation and control networks. Operating over a wide temperature range of -40°C to 85°C and with a supply voltage range from 1.8 V to 3.46 V, it offers robustness for deployment in demanding environments.

The device requires multiple power supply voltages (1.8 V, 2.5 V, or 3.3 V) and is RoHS compliant. It is provided with full duplex and half duplex communication modes enhancing flexibility across different application scenarios in networking, embedded systems, automotive Ethernet solutions, and industrial IoT infrastructures.
