Questions

Is there a KiCad symbol and footprint for the CH571R?

Yes. The symbol is EasyEDA_Cloud:CH571R and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH571R?

TSSOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the CH571R datasheet?

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

Where can I order the CH571R?

JLCPCB lists it as part C39831291, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CH571R?

Parts like it in the library: the MSP430FR2311IPW16R by Texas Instruments, the MSP430FR2422IPW16R by Texas Instruments, the S9S08SG16E1MTGR by NXP Semiconductors and the MSP430FR2100IPW16R by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
