Questions

Is there a KiCad symbol and footprint for the STM32F446RCT6?

Yes. The symbol is MCU_ST_STM32F4:STM32F446RCTx and the footprint Package_QFP:LQFP-64_10x10mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32F446RCT6?

LQFP-64(10x10), with 64 pins. Its footprint is drawn on this page.

Where is the STM32F446RCT6 datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the STM32F446RCT6?

JLCPCB lists it as part C915971, with 1,442 in stock; the sellers' links on this page open their listings.

What can replace the STM32F446RCT6?

Parts like it in the library: the AT32F403ARCT7 by ARTERY, the AT32F403ARGT7 by ARTERY, the HC32F460KCTA-LQFP64 by XHSC and the HC32F460KETA-LQFP64 by XHSC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
