Is there a KiCad symbol and footprint for the ATTINY9-TSH?
Yes. The symbol is MCU_Microchip_ATtiny:ATtiny9-TS and the footprint Package_TO_SOT_SMD:SOT-23-6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ATTINY9-TSH?
SOT-23-6, with 6 pins. Its footprint is drawn on this page.
Where is the ATTINY9-TSH datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the ATTINY9-TSH?
JLCPCB lists it as part C1857424, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ATTINY9-TSH?
Parts like it in the library: the FT61F020-URT by FMD, the PIC10LF322-I/OT by Microchip Technology, the FT60F210-URT by FMD and the XMC8P53S6 by Shenzhen Fuman Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
