Questions

Is there a KiCad symbol and footprint for the CH568L?

Yes. The symbol is EasyEDA_Cloud:CH568L and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH568L?

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

Where is the CH568L datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH568L?

JLCPCB lists it as part C963142, with 238 in stock; the sellers' links on this page open their listings.

What can replace the CH568L?

Parts like it in the library: the GD32F303CCT6 by GigaDevice, the N32G430C8L7 by Nations Technologies Inc, the GD32F303CBT6 by GigaDevice Semicon Beijing and the STM32G431CBT6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
