KSZ8995XA4

Specialized ICS Overview

The KSZ8995XA4 is a 10/100 Mbps integrated Ethernet switch manufactured by Microchip Technology. It features five MACs and five Fast Ethernet transceivers within a single package. The device utilizes a shared memory-based switch fabric with fully non-blocking configuration and offers 1.4 Gbps high-performance memory bandwidth. It supports comprehensive LED control, 7-wire SNI for legacy MAC interfaces, and dual MII interfaces. The component operates with supply voltages ranging from 1.7 V to 3.45 V and is housed in a 128-pin PQFP (14x20 mm) surface-mount package.

Specialized ICS Feature Summary

• Integrated 5-port 10/100 Ethernet switch with PHY and frame buffers
• Shared memory switch fabric providing 1.4 Gbps non-blocking bandwidth
• Supports VLAN, QoS priority, management, and MIB counters
• Dual MII interfaces and CPU control/data interfaces

Specialized ICS Applications

• Low port count cost-sensitive 10/100 Mbps switch systems
• Port switching and network interface applications
• Emerging Fast Ethernet applications requiring managed Layer 2 features

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and moisture sensitivity level. Ensure compatibility with the required supply voltage range of 1.7 V to 3.45 V during design integration. Confirm that the 128-PQFP footprint matches the target PCB layout dimensions of 14x20 mm.

Specialized ICS Selection Notes

Select this component for designs requiring a highly integrated Layer 2 managed switch with optimized bill of materials. It is suitable for applications needing ag/port-based VLAN, QoS, and extensive LED support. Verify that the system architecture can accommodate the dual MII and 7-wire SNI interface requirements for proper MAC connectivity.

Specialized ICS Part Context

This part belongs to the KSZ8995 series of Ethernet ICs from Microchip Technology. It is designed as a cost-effective solution for fast Ethernet networking, offering significant integration by combining switch logic, MACs, and PHYs into one package. The series targets embedded networking solutions where space and component count are critical constraints.

Specialized ICS Replacement Considerations

Consult Microchip's official cross-reference documents for verified substitutes. Ensure any replacement maintains the 128-PQFP package and 10/100 Mbps speed capabilities.
