Questions

Is there a KiCad symbol and footprint for the CH557Q?

Yes. The symbol is EasyEDA_Cloud:CH557Q and the footprint Package_QFP:LQFP-64_7x7mm_P0.4mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH557Q?

LQFP-64(7x7), with 64 pins. Its footprint is drawn on this page.

Where is the CH557Q datasheet?

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

Where can I order the CH557Q?

JLCPCB lists it as part C21713667, with 82 in stock; the sellers' links on this page open their listings.

What can replace the CH557Q?

Parts like it in the library: the CW32L083RCS6 by CW, the M482SIDAE by Nuvoton Tech, the NUC131SD2AE by Nuvoton Tech and the HC32F176KATA-LQ64 by XHSC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
