KSZ8895RQXI-TR

Controllers Overview

The KSZ8895RQXI-TR is a Layer 2 managed, five-port Ethernet switch manufactured by Microchip Technology. It integrates five 10/100Base-T/TX transceivers compliant with IEEE 802.3u standards and supports data rates of 10 Mb/s and 100 Mb/s. The device operates within a supply voltage range of 1.14 V to 3.465 V and functions at temperatures between -40°C and +85°C. It utilizes a 128-pin PQFP package and includes interfaces such as MII, RMII, SPI, I2C, and SMI for configuration and management.

Controllers Feature Summary

• Supports up to 128 active VLAN groups with per-port tag insertion or removal capabilities.
• Features a non-blocking shared memory switch fabric with 1.4 Gbps bandwidth and 64 Kbyte frame buffering.
• Provides comprehensive QoS prioritization using 802.1p and DiffServ with programmable weighted fair queuing.
• Includes advanced monitoring features like port mirroring, loopback support, and MIB counters.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with required interface standards before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate humidity sensitivity levels for storage and handling procedures.

Controllers Selection Notes

Select this component for cost-sensitive applications requiring low power consumption and integrated on-chip termination. Consider the RQX variant specifically when RMII interfaces are required for Port 5 connectivity. Evaluate thermal requirements to ensure operation within the specified industrial temperature range.

Controllers Part Context

This part belongs to the KSZ8895 family, which includes MQX, FQX, and MLX variants offering different port configurations and interface options. The RQX model specifically provides RMII interfaces for both MAC and PHY on Port 5, distinguishing it from the MII-based MQX version.
