Microchip 128-Pin PQFP Ethernet Switch IC 1.14V 100 Mbps RGMII RMII MII KSZ8895RQXI

Microchip KSZ8895RQXI is a sophisticated 128-pin PQFP Ethernet Switch IC operating within a supply voltage range of 1.14 V minimum to 1.32 V maximum, delivering a maximum data rate of 100 Mbps. It supports multiple physical layer interfaces including RGMII, RMII, and MII, making it suitable for versatile networking applications.

This device features a fully managed Layer 2 five-port switch with integrated fiber support, optimized for low power consumption and cost-effective deployment in 10/100 Mbps Ethernet networks. Its shared memory-based switch fabric provides 1.4 Gbps memory bandwidth with a non-blocking configuration, ensuring efficient data throughput and minimal packet loss.

The KSZ8895 family supports a static MAC table of up to 32 entries, VLAN tagging, and IEEE 802.1p/q priority traffic handling on a per-port basis, enabling advanced network traffic management. Programmable ingress and egress rate limiting, along with broadcast storm control, enhance network stability and performance.

Compliant with RoHS standards, this IC operates reliably across a wide industrial temperature range from -40°C to 85°C. Its on-chip termination and internal low-dropout (LDO) regulator help reduce the overall system cost and complexity. The device supports IEEE 802.1d rapid spanning tree protocol (RSTP) to maintain efficient network topology dynamics.

Additional features include tail tag mode on port 5, which enables processors to identify the ingress port of packets, increasing system diagnostic and control capabilities. The KSZ8895RQXI is ideal for industrial, commercial, and networking equipment requiring dependable Ethernet switch functionality.
