Questions

Is there a KiCad symbol and footprint for the AT89LP52-20JU?

Yes. The symbol is EasyEDA_Cloud:AT89LP52-20JU and the footprint EasyEDA_Cloud:PLCC-44_L16.6-W16.6-P1.27-LS17.5-T, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AT89LP52-20JU?

PLCC-44(16.6x16.6), with 44 pins. Its footprint is drawn on this page.

Where is the AT89LP52-20JU datasheet?

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

Where can I order the AT89LP52-20JU?

JLCPCB lists it as part C145581, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AT89LP52-20JU?

Parts like it in the library: the AT89S52-24JU by Microchip Technology, the AT80C51RD2-SLRUM by Microchip Technology, the AT89C51CC03UA-SLSUM by Microchip Technology and the AT89LP51IC2-20JU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
