Overview
The 93LC66B-E/MS is an EEPROM made by Microchip Technology in a MSOP-8 package with 8 pins. -40℃~+125℃ 2.5V~5.5V 2MHz 4Kbit 6ms MSOP-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (Memory_EEPROM:93LCxxB, from KiCad's library) and its footprint (Package_SO:MSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1352264).
