Questions
Is there a KiCad symbol and footprint for the 23K256-I/SN?
Yes. The symbol is EasyEDA_Cloud:GT30L24T3Y and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 23K256-I/SN?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the 23K256-I/SN datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the 23K256-I/SN?
JLCPCB lists it as part C219986, with 7 in stock; the sellers' links on this page open their listings.
What can replace the 23K256-I/SN?
Parts like it in the library: the PM002MNIATR by Shanghai Siproin Microelectronics, the 23K256T-I/SN by Microchip Technology, the 23LCV512-I/SN by Microchip Technology and the VTI7064MSME by Vilsion Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 23K256-I/SN?
3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
