Is there a KiCad symbol and footprint for the HT1623?
Yes. The symbol is EasyEDA_Cloud:HT1623 and the footprint EasyEDA_Cloud:QFP-100_L20.0-W14.0-P0.65-LS17.2-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT1623?
QFP-100(14x20), with 100 pins. Its footprint is drawn on this page.
Where is the HT1623 datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT1623?
JLCPCB lists it as part C14125, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HT1623?
Parts like it in the library: the HT16C22A LQFP-48 by Holtek Semicon, the TM1622B by TM, the HT16C23A-64LQFP-7*7 by Holtek Semicon and the HG1622B-LQ44 by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
