Microchip Ethernet Switch IC 128-Pin PQFP, 100 Mbps RGMII, RMII, MII, 1.14V - 1.32V KSZ8895RQXI

Microchip KSZ8895RQXI is a advanced 128-pin PQFP Ethernet Switch IC designed for 10/100 Mbps five-port systems with low power consumption and cost efficiency. It supports communication interfaces such as RGMII, RMII, and MII and operates at supply voltages between 1.14 V and 1.32 V. This device integrates features like internal LDO regulator and on-chip termination to minimize overall system cost while providing robust Layer 2 managed switching capabilities.

With a static MAC table capacity of up to 32 entries, this switch manages network traffic effectively by supporting VLAN ID tag and untagged options on a per-port basis. It features IEEE 802.1p/q tag insertion or removal for prioritized network traffic management. The KSZ8895RQXI includes programmable rate limiting at both ingress and egress ports along with jitter-free per packet rate control to ensure smooth traffic flow.

The switch is equipped with broadcast storm protection with controllable percentage thresholds and supports IEEE 802.1d rapid spanning tree protocol (RSTP) for network redundancy and loop avoidance. The architecture features a 1.4 Gbps high-performance shared memory-based switch fabric providing fully non-blocking configuration for efficient data throughput.

Tail tag mode support at port 5 allows the processor to identify the ingress port handling each packet, enhancing network diagnostics. The wide operating temperature range from -40°C to 85°C and RoHS compliance make this IC suitable for demanding industrial, networking, and communications applications.

This Ethernet Switch IC is ideal for use in industrial networking equipment, embedded systems, networking infrastructure devices, and telecommunications hardware requiring reliable and efficient Layer 2 switching solutions.
