Overview
The 25LC640-I/P is an EEPROM made by Microchip Technology in a PDIP-8 package with 8 pins. PDIP-8 Pre-ordered Chips ROHS.
PCBKit's library has its KiCad symbol (Memory_EEPROM:25LCxxx, from KiCad's library) and its footprint (Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1348829).
