Is there a KiCad symbol and footprint for the ST7538Q?
Yes. The symbol is EasyEDA_Cloud:ST7538QTR and the footprint Package_QFP:TQFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST7538Q?
TQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.
Where is the ST7538Q datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST7538Q?
JLCPCB lists it as part C1544469, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ST7538Q?
Parts like it in the library: the AMIS-49250-XTP by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
