Questions

Is there a KiCad symbol and footprint for the CH592X?

Yes. The symbol is EasyEDA_Cloud:CH592X_C42442063 and the footprint EasyEDA_Cloud:QFN-32_L4.0-W4.0-P0.40-BL-EP2.8, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH592X?

QFN-32-EP(4x4), with 33 pins. Its footprint is drawn on this page.

Where is the CH592X datasheet?

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

Where can I order the CH592X?

JLCPCB lists it as part C42442063, with 2,269 in stock; the sellers' links on this page open their listings.

What can replace the CH592X?

Parts like it in the library: the CC1310F128RSMR by Texas Instruments, the HC32F190FCUA-QFN32TR by XHSC, the STC8H1K28-36I-QFN32 by STC Micro and the FU6522N by Fortior Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
