KSZ8895MQXC

Controllers Overview

The KSZ8895MQXC is a Layer 2 managed, five-port Ethernet switch integrated with five MACs and five PHYs compliant with IEEE 802.3u standards. It operates at data rates of 10 Mb/s and 100 Mb/s using 10BASE-T and 100BASE-TX protocols. The device utilizes a 128-pin PQFP package and supports MII and RMII interfaces for CPU connectivity. Power requirements include a minimum voltage of 1.8 V and a maximum of 3.3 V, with a maximum power consumption of 107 mA. It functions within a commercial temperature range of 0°C to +70°C.

Controllers Feature Summary

• Supports up to 128 active VLAN groups with per-port tag insertion or removal based on ingress port rules.
• Provides non-blocking switching fabric with 1.4 Gbps memory bandwidth and 64 Kbyte frame buffering.
• Enables comprehensive management via SPI, I2C, and SMI interfaces with extensive register access.
• Includes advanced QoS features such as 802.1p prioritization, DiffServ support, and weighted fair queuing.

Controllers Applications

• VoIP Phone systems
• Industrial Control networks
• SOHO Residential Gateways

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure compatibility with the required interface configuration, as the MQX variant specifically provides MII interfaces for Port 5. Cross-reference the datasheet revision to identify any silicon errata or operational clarifications relevant to the production batch.

Controllers Selection Notes

Select this component when a cost-sensitive, low-power solution for five-port 10/100 Mbps networking is required. The MQX designation indicates the availability of separate MII interfaces for both the Switch MAC and PHY on Port 5, facilitating flexible CPU integration. Consider the commercial temperature range limits when designing for environments exceeding 70°C.

Controllers Part Context

This part belongs to the KSZ8895 family of integrated Ethernet switches manufactured by Microchip Technology. The family includes variants with different interface configurations, such as RMII (RQX) and fiber ports (FQX). All variants share the same core switching architecture and management capabilities but differ in physical layer connectivity options.
