Is there a KiCad symbol and footprint for the HT66F018?
Yes. The symbol is EasyEDA_Cloud:HT66F018_C81480 and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT66F018?
SOP-20-300mil, with 20 pins. Its footprint is drawn on this page.
Where is the HT66F018 datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT66F018?
JLCPCB lists it as part C113544, with 76 in stock; the sellers' links on this page open their listings.
What can replace the HT66F018?
Parts like it in the library: the STC15W408AS-35I-SOP20 by STC Micro, the STC12C5204AD-35I-SOP20 by STC Micro, the ATTINY1616-SN by Microchip Technology and the SC92F7352M20U by SOC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
