Questions

Is there a KiCad symbol and footprint for the ATMEGA8U2-MU?

Yes. The symbol is MCU_Microchip_ATmega:ATmega8U2-M and the footprint Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.1x3.1mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA8U2-MU?

QFN-32(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the ATMEGA8U2-MU datasheet?

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

Where can I order the ATMEGA8U2-MU?

JLCPCB lists it as part C111447, with 16 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA8U2-MU?

Parts like it in the library: the ATMEGA328P-MUR by Microchip Technology, the ATMEGA88PA-MU by Microchip Technology, the ATMEGA168PA-MU by Microchip Technology and the ATMEGA328PB-MN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
