Questions

Is there a KiCad symbol and footprint for the STM32L552RET6Q?

Yes. The symbol is MCU_ST_STM32L5:STM32L552RETxQ 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 STM32L552RET6Q?

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

Where is the STM32L552RET6Q datasheet?

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

Where can I order the STM32L552RET6Q?

JLCPCB lists it as part C3231051, with 1 in stock; the sellers' links on this page open their listings.

What can replace the STM32L552RET6Q?

Parts like it in the library: the GD32F303RCT6 by GigaDevice, the AT32F403ARCT7 by ARTERY, the STM32G474RBT3 by STMicroelectronics and the AT32F403ARGT7 by ARTERY. Check their datasheets: a part that fits the footprint may still differ in its ratings.
