Questions

Is there a KiCad symbol and footprint for the ATTINY3216-SF?

Yes. The symbol is MCU_Microchip_ATtiny:ATtiny3216-S and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATTINY3216-SF?

SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.

Where is the ATTINY3216-SF datasheet?

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

Where can I order the ATTINY3216-SF?

JLCPCB lists it as part C1340355, with 86 in stock; the sellers' links on this page open their listings.

What can replace the ATTINY3216-SF?

Parts like it in the library: the STC15W408AS-35I-SOP20 by STC Micro, the FT61F145A-RB by FMD, the STC12C5204AD-35I-SOP20 by STC Micro and the ATTINY1616-SN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
