Questions
Is there a KiCad symbol and footprint for the ST3243CPR?
Yes. The symbol is EasyEDA_Cloud:MAX3245EEWI+ and the footprint Package_SO:SSOP-28_5.3x10.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST3243CPR?
SSOP-28, with 28 pins. Its footprint is drawn on this page.
Where is the ST3243CPR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST3243CPR?
JLCPCB lists it as part C283495, with 5 in stock; the sellers' links on this page open their listings.
What can replace the ST3243CPR?
Parts like it in the library: the SP213EEA-L/TR by MaxLinear, the SP3243EEA-L/TR by MaxLinear, the SP3243EBEA-L/TR by MaxLinear and the SP3243EUEA-L/TR by MaxLinear. Check their datasheets: a part that fits the footprint may still differ in its ratings.
