Questions

Is there a KiCad symbol and footprint for the ATMEGA32A-PU?

Yes. The symbol is MCU_Microchip_ATmega:ATmega32A-P and the footprint Package_DIP:DIP-40_W15.24mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA32A-PU?

DIP-40, with 40 pins. Its footprint is drawn on this page.

Where is the ATMEGA32A-PU datasheet?

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

Where can I order the ATMEGA32A-PU?

JLCPCB lists it as part C12703, with 56 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA32A-PU?

Parts like it in the library: the ATMEGA1284P-PU by Microchip Technology, the ATMEGA16A-PU by Microchip Technology, the PIC16C774-I/P by Microchip Technology and the ATMEGA644P-20PU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
