Questions

Is there a KiCad symbol and footprint for the EM3585-RT?

Yes. The symbol is EasyEDA_Cloud:EM351-RTR and the footprint EasyEDA_Cloud:QFN-48_L7.0-W7.0-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 EM3585-RT?

QFN-48-EP(7x7), with 49 pins. Its footprint is drawn on this page.

Where is the EM3585-RT datasheet?

Silicon Labs publishes it: the Datasheet link on this page opens it.

Where can I order the EM3585-RT?

JLCPCB lists it as part C430188, with 0 in stock; the sellers' links on this page open their listings.

What can replace the EM3585-RT?

Parts like it in the library: the EFR32MG12P432F1024IM48-CR by Silicon Labs, the EFR32MG12P433F1024GM48-C by Silicon Labs, the EFR32BG12P132F1024GM48-C by Silicon Labs and the EFR32BG12P432F1024GM48-CR by Silicon Labs. Check their datasheets: a part that fits the footprint may still differ in its ratings.
