KSZ8995MI

Specialized ICS Overview

The KSZ8995MI is a Layer-2 managed switch IC from Microchip Technology, housed in a 128-pin PQFP package. It integrates five MAC units and five Fast Ethernet transceivers compliant with IEEE 802.3u. The device supports 10BaseT and 100BaseTX on all ports, with Ports 4 and 5 additionally supporting 100BaseFX fiber interfaces. It features a shared memory-based non-blocking switch fabric with 1.4 Gbps bandwidth and an on-chip 64 Kbyte frame buffer. Operating voltages include a 1.8 V core and 2.5 V or 3.3 V I/O. The component operates within a commercial temperature range of 0 °C to +70 °C.

• Managed media converters for fiber-to-copper conversion

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm the temperature grade and lead-free status. The 'I' suffix typically denotes industrial temperature ratings, but official documentation should be consulted to ensure compatibility with the intended operating environment and regulatory requirements.

Specialized ICS Selection Notes

Select this component for cost-sensitive applications requiring integrated switching and PHY functionality without external components. Ensure the design accommodates the dual MII interface requirements for CPU control. Verify that the system power supply can provide the necessary 1.8 V core and 2.5 V/3.3 V I/O rails simultaneously.
