Questions

Is there a KiCad symbol and footprint for the TM1622B?

Yes. The symbol is EasyEDA_Cloud:TM1622B-LQFP64(14_20) and the footprint EasyEDA_Cloud:LQFP-64_L7.0-W7.0-P0.40-LS9.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1622B?

LQFP-52(14x14), with 64 pins. Its footprint is drawn on this page.

Where is the TM1622B datasheet?

TM publishes it: the Datasheet link on this page opens it.

Where can I order the TM1622B?

JLCPCB lists it as part C5174671, with 3,866 in stock; the sellers' links on this page open their listings.

What can replace the TM1622B?

Parts like it in the library: the HT16C22A LQFP-48 by Holtek Semicon, the HT16C23A-64LQFP-7*7 by Holtek Semicon, the HG1622B-LQ44 by HGSEMI and the HT16C23A-48LQFP by Holtek Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
