Is there a KiCad symbol and footprint for the ETA355DCSU?
Yes. The symbol is EasyEDA_Cloud:ETA355DCSU and the footprint EasyEDA_Cloud:CSP-20_L2.0-W1.6-R5-C4-P0.40-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ETA355DCSU?
CSP-20, with 20 pins. Its footprint is drawn on this page.
Where is the ETA355DCSU datasheet?
etasolution publishes it: the Datasheet link on this page opens it.
Where can I order the ETA355DCSU?
JLCPCB lists it as part C7465542, with 1,408 in stock; the sellers' links on this page open their listings.
What can replace the ETA355DCSU?
Parts like it in the library: the ETA355ECSU by etasolution. Check their datasheets: a part that fits the footprint may still differ in its ratings.
