Overview
The 93LC46B/SN is an EEPROM made by Microchip Technology in a SOIC-8 package with 8 pins. 0℃~+70℃ 1,000,000 cycles 1Kbit 2.5V~6V 200 Years 2MHz 6ms SPI SOIC-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (Memory_EEPROM:93LCxxB, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 105 are in stock at JLCPCB (part C1348804). 1 open-source board in 1 repository on GitHub use it.
