Overview
The 25LC640X-I/ST is an EEPROM made by Microchip Technology in a TSSOP-8 package with 8 pins. -40℃~+85℃ 2.5V~5.5V 2MHz 5ms 64Kbit TSSOP-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (Memory_EEPROM:25LCxxx, from KiCad's library) and its footprint (Package_SO:TSSOP-8_4.4x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1349035).
