Questions

Is there a KiCad symbol and footprint for the STM32L552ZCT6Q?

Yes. The symbol is MCU_ST_STM32L5:STM32L552ZCTxQ and the footprint Package_QFP:LQFP-144_20x20mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32L552ZCT6Q?

LQFP-144(20x20), with 144 pins. Its footprint is drawn on this page.

Where is the STM32L552ZCT6Q datasheet?

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

Where can I order the STM32L552ZCT6Q?

JLCPCB lists it as part C1236657, with 4 in stock; the sellers' links on this page open their listings.

What can replace the STM32L552ZCT6Q?

Parts like it in the library: the STM32F417ZGT6 by STMicroelectronics, the STM32L4S5ZIT6 by STMicroelectronics, the STM32F205ZGT7 by STMicroelectronics and the STM32F437ZIT7 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
