Is there a KiCad symbol and footprint for the ATTINY404-SSN?
Yes. The symbol is MCU_Microchip_ATtiny:ATtiny404-SS and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ATTINY404-SSN?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the ATTINY404-SSN datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the ATTINY404-SSN?
JLCPCB lists it as part C1339119, with 611 in stock; the sellers' links on this page open their listings.
What can replace the ATTINY404-SSN?
Parts like it in the library: the PY32F002BD15S6TU by PUYA, the PIC16F1503-I/SL by Microchip Technology, the PIC16F1824-I/SL by Microchip Technology and the PIC16F676-I/SL by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
