Questions

Is there a KiCad symbol and footprint for the ATMEGA645-16MU?

Yes. The symbol is EasyEDA_Cloud:ATMEGA325V-8MUR and the footprint EasyEDA_Cloud:QFN-64_L9.0-W9.0-P0.50-TL-EP5.4, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA645-16MU?

QFN-64-EP(9x9), with 65 pins. Its footprint is drawn on this page.

Where is the ATMEGA645-16MU datasheet?

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

Where can I order the ATMEGA645-16MU?

JLCPCB lists it as part C1342062, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA645-16MU?

Parts like it in the library: the PIC32MX370F512H-I/MR by Microchip Technology, the AT90CAN128-15M by Microchip Technology, the AT90CAN32-15MT1 by Microchip Technology and the ATMEGA169-16MU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
