KSZ8795CLXIC

Controllers Overview

The KSZ8795CLXIC is a Layer 2-managed, highly integrated 5-port Ethernet switch manufactured by Microchip Technology. It features four 10/100BASE-T/TX MAC/PHY transceivers and one Gigabit GMAC with configurable GMII, RGMII, MII, or RMII interfaces for the fifth port. The device operates within a commercial temperature range of 0°C to +70°C and an industrial range of -40°C to +85°C. Power supply requirements include VDDAT at 3.3V or 2.5V, VDDIO at 3.3V, 2.5V, or 1.8V, and a core voltage of 1.2V. It utilizes an 80-pin LQFP package.

Controllers Feature Summary

• Integrated management capabilities including non-blocking store-and-forward switch fabric, 1024-entry forwarding table, and hardware support for Rapid Spanning Tree Protocol (RSTP).
• Robust PHY ports featuring HP Auto MDI/MDI-X crossover support, on-chip termination resistors, internal biasing, and IEEE 802.1az Energy Efficient Ethernet (EEE) compliance.
• Advanced switching functions such as IEEE 802.1q VLAN support for up to 128 active groups, per-port QoS prioritization, programmable rate limiting, and ACL-based security filtering.
• Flexible configuration via high-speed SPI interface or MDC/MDIO MIIM interface, supported by I/O pin strapping facilities for register configuration during reset.

Controllers Applications

• Industrial Ethernet applications employing IEEE 802.3-compliant MACs such as Ethernet/IP, PROFINET, and Modbus TCP.
• Broadband gateways, firewalls, VPNs, and integrated DSL/cable modems requiring cost-sensitive managed switching.
• VoIP phones, set-top boxes, game boxes, and IPTV platforms.
• Wireless LAN access points combined with gateway functionality.
• Standalone 10/100 switches and networked measurement and control systems.

Controllers Procurement Notes

Verify the specific suffix 'IC' against official Microchip documentation to confirm it denotes the industrial temperature grade (-40°C to +85°C) and RoHS compliance status. Ensure the ordering part number matches the exact datasheet revision required for your design. Confirm availability through authorized distributors as supply chain conditions may vary.

Controllers Selection Notes

Select this component when a cost-effective, Layer 2 managed switch is required with four copper ports and one gigabit uplink. It is suitable for designs needing flexible CPU interface options via GMII/RGMII/MII/RMII. Consider its power management features like EEE and Wake-on-LAN for energy-efficient applications. Verify that the 80-pin LQFP package fits the PCB layout constraints.

Controllers Part Context

The KSZ8795CLXIC belongs to the KSZ8795 family of integrated 5-port managed switches from Microchip Technology. This series is designed to reduce system costs while providing extensive management features. The 'CLX' designation typically refers to the standard commercial/industrial variants in the LQFP-80 package, forming a key solution for broadband and industrial networking equipment.

Controllers Replacement Considerations

Consult Microchip's official obsolescence notices and cross-reference tools for direct replacements. Potential alternatives within the same portfolio should be evaluated based on pin compatibility and feature parity. No public substitute part numbers are confirmed in the provided source material.
