The Microchip highly-integrated, IEEE 802.3 compliant networking device that incorporates a layer-2 managed high-performance Ethernet switch, five 10BASE-T/Te/100BASE-TX physical layer transceivers (PHYs) and associated MAC units, and two MAC ports with individually configurable RGMII/MII/RMII interfaces for direct connection to a host processor/controller, another Ethernet switch, or an Ethernet PHY transceiver. This device incorporates full hardware support for the IEEE 1588v2 precision time protocol (PTP), including hardware time-stamping at all PHY-MAC interfaces, and a high-resolution hardware “PTP clock”. IEEE 1588 provides sub microsecond synchronization for a range of industrial Ethernet applications.

Requires 2 to 3 power supply for 1.8 V, 2.5 V, or 3.3 V
Non-blocking wire-speed Ethernet switch fabric supports 1 Gbps on RGMII
Full-featured forwarding and filtering control, including port-based Access Control List filtering
Full VLAN and QoS support
Traffic prioritization with per-port ingress/egress queues and by traffic classification
