Product Details
KSZ8993M - Three-Port 10/100 Managed Ethernet Switch
KSZ8993M from Microchip Technology is an integrated three-port Fast Ethernet switch with two 10/100 PHYs and a configurable host/MAC port in a 128-pin PQFP.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
KSZ8993M integrates two IEEE 802.3 10BASE-T/100BASE-TX PHYs, three MACs and a Layer 2 managed switch. It can operate under host control or from straps and EEPROM.
Key Advantages
Combines two copper PHY ports and a third MAC interface with switching, filtering and QoS functions.
Supports managed SPI, I2C, SMI or MIIM control as well as unmanaged strap/EEPROM startup.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Three-port managed Fast Ethernet switch
Two 10/100 PHY ports, MII/RMII host port, SPI/I2C/SMI/MIIM management
3.3 V I/O with device-specific core rails; industrial networking temperature options vary by order code
128-BFQFP
Package & Footprint
This ordering code uses the 128-BFQFP package.

Replacement Considerations
KSZ8993MI 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 linked KSZ8993MI belongs to the same switch family but has a different temperature/order grade. Confirm electrical, lifecycle and qualification requirements.
Applications
Adds two external Fast Ethernet ports and a host-facing MAC port.
Provides managed switching, VLAN/QoS and cable diagnostics in compact controllers.
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
