Questions

Is there a KiCad symbol and footprint for the AT24CS64-XHM-B?

Yes. The symbol is Memory_EEPROM:AT24CS64-XHM and the footprint Package_SO:TSSOP-8_4.4x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AT24CS64-XHM-B?

TSSOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the AT24CS64-XHM-B datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the AT24CS64-XHM-B?

JLCPCB lists it as part C1350547, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AT24CS64-XHM-B?

Parts like it in the library: the BL24C256A-SFRC by BL, the BL24C32A-SFRC by BL, the BL24C64A-SFRC by BL and the AT24C04C-XHM-T by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
