Questions

Is there a KiCad symbol and footprint for the CH348L?

Yes. the footprint Package_QFP:LQFP-100_14x14mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH348L?

LQFP-100(14x14), with 100 pins. Its footprint is drawn on this page.

Where is the CH348L datasheet?

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

Where can I order the CH348L?

JLCPCB lists it as part C2979160, with 9 in stock; the sellers' links on this page open their listings.

What can replace the CH348L?

Parts like it in the library: the CY7C68320C-100AXA by Infineon Technologies, the CY7C68320C-100AXC by Infineon Technologies and the CY7C64714-100AXC by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CH348L?

4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
