KSZ8995XA

Specialized ICS Overview

The KSZ8995XA is a Layer-2 integrated switch featuring five Fast Ethernet MACs and transceivers compliant with IEEE 802.3u. It supports 10BASE-T, 100BASE-TX on all ports, and 100BASE-FX on ports 4 and 5. The device includes a non-blocking shared memory switch fabric, an on-chip 64Kbyte frame buffer, and a dedicated 1K unicast address lookup engine. Power requirements are 1.8V for the core, 3.3V for digital I/O, and 2.5V or 3.3V for analog I/O. It operates within a commercial temperature range of 0°C to +70°C.

Specialized ICS Feature Summary

• Integrated 5-port 10/100 switch with dual MII configuration (MII-Switch and MII-P5) for flexible system integration.
• Supports QoS/CoS prioritization via per-port settings, 802.1p, and DiffServ-based schemes.
• Includes hardware power-down support and per-port software power-save with idle link detection.
• Features automatic MDI/MDI-X crossover, broadcast storm protection, and VLAN ID tag/untag options.

Specialized ICS Applications

• Broadband Gateway/Firewall/VPN
• Integrated DSL or Cable Modem Multi-Port Router
• Wireless LAN Access Point Plus Gateway
• Standalone 10/100 Switch
• Media Converter

Specialized ICS Procurement Notes

Verify the specific ordering suffix against Microchip documentation to confirm package type and temperature grade. Confirm that the 'XA' designation aligns with the intended unmanaged switch configuration using I/O strapping or EEPROM programming. Ensure supply chain sources provide valid RoHS compliance data as specified in the manufacturer's environmental files.

Specialized ICS Selection Notes

Select this component for cost-sensitive, low port count systems requiring integrated PHYs and frame buffers. The dual MII interface allows optimization for broadband router designs by decoupling the fifth port. Verify that the required voltage levels (1.8V core, 3.3V digital, 2.5V/3.3V analog) match the target system power rails. Ensure the application does not require managed switching features, as this model is optimized for unmanaged configurations.

Specialized ICS Part Context

The KSZ8995XA belongs to the KSZ8995 family of integrated Ethernet switches. It is pin-compatible with the managed KSZ8995M but is optimized for unmanaged solutions where configuration is handled via I/O strapping or external EEPROM. The device utilizes 0.18 µm CMOS technology to achieve low power consumption while maintaining wire-speed performance.
