Questions

Is there a KiCad symbol and footprint for the AT91SAM9G20B-CU?

Yes. The symbol is EasyEDA_Cloud:AT91SAM9G20B-CU and the footprint EasyEDA_Cloud:LFBGA-217_L15.0-W15.0-R17-C17-P0.80-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AT91SAM9G20B-CU?

LFBGA-217, with 217 pins. Its footprint is drawn on this page.

Where is the AT91SAM9G20B-CU datasheet?

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

Where can I order the AT91SAM9G20B-CU?

JLCPCB lists it as part C40255, with 169 in stock; the sellers' links on this page open their listings.

What can replace the AT91SAM9G20B-CU?

Parts like it in the library: the AT91SAM9G25-CU by Microchip Technology, the AT91SAM9G15-CU by Microchip Technology, the AT91SAM9X25-CU by Microchip Technology and the AT91SAM9G35-CU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
