Yes. The symbol is EasyEDA_Cloud:SP3243EY-L and the footprint EasyEDA_Cloud:TSSOP-28_L9.7-W4.4-P0.65-LS6.4-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
JLCPCB lists it as part C3212849, with 0 in stock; the sellers' links on this page open their listings.
