KSZ8863MLLI-TR

Controllers Overview

The KSZ8863MLLI-TR is a highly integrated 3-port managed Ethernet switch IC manufactured by Microchip Technology. It features two 10/100BASE-T/TX transceivers and one MII interface, housed in a 48-pin LQFP package. The device supports data rates of 10 Mb/s and 100 Mb/s with full-duplex and half-duplex operation. Operating voltage ranges from 3.135 V to 3.465 V, while the digital I/O supply (VDDIO) supports 3.3 V, 2.5 V, or 1.8 V. It operates within an industrial temperature range of -40°C to +85°C.

Controllers Feature Summary

• Supports IEEE 802.1q VLAN for up to 16 groups with per-port tag insertion or removal options.
• Includes bypass mode that sustains switching between Port 1 and Port 2 when the CPU enters sleep mode.
• Provides comprehensive configuration access via SMI, MIIM, SPI, and I2C interfaces.
• Features LinkMD TDR-based cable diagnostics for identifying copper cabling faults.

Controllers Applications

• VoIP Phone
• Set-Top Box / Game Box
• Automotive Systems
• Industrial Control
• IPTV POF

Controllers Procurement Notes

Verify the specific ordering suffix '-TR' indicates tape-and-reel packaging rather than tray packaging. Confirm the 'I' suffix denotes the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the required VDDIO voltage selection (3.3V, 2.5V, or 1.8V) for your system design before procurement.

Controllers Selection Notes

Select this component if your design requires a managed switch with an MII interface for the third port. Compare against the KSZ8863RLL variant if an RMII interface is preferred instead of MII. Consider the KSZ8863FLL if fiber connectivity is needed. Verify power supply requirements for the internal 1.8V LDO regulator derived from VDDIO.

Controllers Part Context

This part belongs to the KSZ8863 family of 3-port 10/100 Mbps switches. The MLL variant specifically provides two copper PHY ports and one MII interface. Other family members include the RLL (RMII interface) and FLL (fiber port) variants. All share similar core switching fabric and management features.
