Is there a KiCad symbol and footprint for the 25LC256-I/P?
Yes. The symbol is Memory_EEPROM:25LCxxx and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 25LC256-I/P?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the 25LC256-I/P datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the 25LC256-I/P?
JLCPCB lists it as part C511271, with 68 in stock; the sellers' links on this page open their listings.
What can replace the 25LC256-I/P?
Parts like it in the library: the 25AA256-I/P by Microchip Technology, the 25AA320A-I/P by Microchip Technology, the 25AA640A-I/P by Microchip Technology and the 25LC320A-I/P by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
