Questions
Is there a KiCad symbol and footprint for the CH579F?
Yes. The symbol is EasyEDA_Cloud:CH579F and the footprint EasyEDA_Cloud:QFN-28_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 CH579F?
QFN-28-EP(4x4), with 29 pins. Its footprint is drawn on this page.
Where is the CH579F datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH579F?
JLCPCB lists it as part C481975, with 1 in stock; the sellers' links on this page open their listings.
What can replace the CH579F?
Parts like it in the library: the CH32V305GBU6 by WCH (Nanjing Qinheng Microelectronics), the GD32E230G8U6TR by GigaDevice Semicon Beijing, the GD32F310G8U6TR by GigaDevice Semicon Beijing and the CH582F by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
