Product Details
KSZ8995MAI - Five-Port Managed Fast Ethernet Switch
KSZ8995MAI from Microchip Technology / Micrel is an industrial-temperature, five-port 10/100 Mb/s Layer 2 managed Ethernet switch in a 128-pin PQFP, supplied in trays.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
KSZ8995MAI integrates five Fast Ethernet PHYs and MACs with a nonblocking switch fabric, address lookup and frame buffering. The MA variant supports 100BASE-FX on ports 4 and 5, with management through serial interfaces and MII connectivity.
Key Advantages
Combines five 10/100 Ethernet transceivers and MACs with a nonblocking switch fabric.
Provides VLAN, QoS, MIB counters and port management for compact network systems.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Five-port managed Layer 2 Fast Ethernet switch
Five Ethernet PHY ports, dual MII paths, SPI and MDIO management
1.8 V core and analog rails; 3.3 V digital/analog I/O; -40 C to +85 C industrial range
128-BFQFP
Package & Footprint
This ordering code uses the 128-BFQFP package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
KSZ8995MA is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
The manufacturer lists KSZ8995MAI as the -40 C to +85 C industrial order code and KSZ8995MA as 0 C to +70 C. The linked part shares the MA family and PQFP package, but its narrower qualified temperature range must be checked before substitution.
Applications
Combines multiple copper Fast Ethernet ports with managed traffic features.
Uses MA-family fiber-capable ports where the full optical design is verified.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
Five-port managed Layer 2 Fast Ethernet switch
What package is used?
128-BFQFP
Can the related part be substituted directly?
No. Validate all electrical, mechanical and configuration differences first.
Is the package image ready?
No. The registered package JPG is currently missing.
Engineering Notice
Use the latest manufacturer documentation for schematic, PCB, thermal and production approval. Distributor attributes are useful for sourcing but do not replace the official data sheet.
