Overview

The KSZ8997 is a microcontroller made by Microchip Technology in a PQFP-128(20x14) package with 128 pins. External pin reset (NRST) PQFP-128(20x14) Ethernet Switches ROHS.

PCBKit's library has its KiCad symbol (Analog & Interface:KSZ8997, from CERN's library) and its footprint (Package_QFP:PQFP-128_28x28mm_P0.8mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C639496).

Questions

Is there a KiCad symbol and footprint for the KSZ8997?

Yes. The symbol is Analog & Interface:KSZ8997 and the footprint Package_QFP:PQFP-128_28x28mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the KSZ8997?

PQFP-128(20x14), with 128 pins. Its footprint is drawn on this page.

Where is the KSZ8997 datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the KSZ8997?

JLCPCB lists it as part C639496, with 0 in stock; the sellers' links on this page open their listings.

What can replace the KSZ8997?

Parts like it in the library: the CY7C68013A-128AXI by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
