KSZ8995MA

Specialized ICS Overview

The KSZ8995MA is a Layer 2 managed switch IC featuring five integrated MACs and fast Ethernet transceivers compliant with IEEE 802.3u. It supports 10BASE-T, 100BASE-TX, and 100BASE-FX media types. The device utilizes a shared memory-based non-blocking switch fabric with 1.4 Gbps bandwidth and includes an on-chip 64 Kbyte frame buffer. Operating voltages are 1.8 V for the core and 3.3 V for digital/analog I/O. It operates within a commercial temperature range of 0°C to +70°C in a 128-pin PQFP package.

Specialized ICS Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific ordering suffix matches the required temperature grade and package variant. Ensure supply chain documentation aligns with current manufacturing standards.

Specialized ICS Selection Notes

Select this model for cost-sensitive low port count applications requiring fiber connectivity. Ports 4 and 5 specifically support 100BASE-FX. Verify interface compatibility with dual MII or legacy SNI requirements before integration into the system design.

Specialized ICS Part Context

This component belongs to the KSZ8995 family of integrated Ethernet switches. It shares architectural similarities with the KSZ8995FQ but differs in fiber port allocation. The MA suffix denotes the commercial temperature grade version of the Micrel/KSZ8995 series.
