Overview
The 25AA040AX-I/ST is an EEPROM made by Microchip Technology in a TSSOP-8 package with 8 pins. -40℃~+85℃ 1.8V~5.5V 10MHz 4Kbit 5ms TSSOP-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:CAT25C128S, from EasyEDA) and its footprint (Package_SO:TSSOP-8_4.4x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1351310).
