Questions

Is there a KiCad symbol and footprint for the ATMEGA3209-AF?

Yes. The symbol is MCU_Microchip_ATmega:ATmega3209-A and the footprint Package_QFP:TQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA3209-AF?

TQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the ATMEGA3209-AF datasheet?

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

Where can I order the ATMEGA3209-AF?

JLCPCB lists it as part C1340135, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA3209-AF?

Parts like it in the library: the STM32F103C8T6 by STMicroelectronics, the STM32F030C8T6 by STMicroelectronics, the STM32G070CBT6 by STMicroelectronics and the STM32G030C8T6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
